95% Diana Vreeland: The Eye Has To Travel

All Critics (62) | Top Critics (24) | Fresh (59) | Rotten (3)

Her life, and her work, transcended what we think of as "fashion." Diana Vreeland: The Eye Has to Travel celebrates a unique and uniquely determined woman.

Many people remember some of Diana Vreeland's famous pronouncements ("I adore pink! It is the navy blue of India!") but few remember actually hearing her speak. The documentary Diana Vreeland: The Eye Has to Travel takes care of that.

For fashionphiles and pop culture vultures, there's much to devour.

Diana Vreeland is both history lesson and sentimental love letter to a fashion titan.

Legendary fashion editor Diana Vreeland was the consummate dreamer, a romantic who never looked back and propelled society forward.

A feast for fashion-history buffs and anyone who applauds unstoppable eccentricity.

An otherwise fine profile of American fashion magazine doyen Diana Vreeland is let down by pedestrian production.

She wanted you to look and look again, and this film is full of images which make you do just that.

There's something marvellously comic about her, an effect reinforced by her refined yet raucous baritone voice.

This pleasurable documentary is jammed packed with images from magazines, photoshoots and newsreels of a life well lived, but also lots of historical footage of the life Vreeland imagined she had too.

...more of an energetic and affectionate sketch than a revealing portrait of this oversized personality, but one has to wonder if the woman who celebrated glittering surfaces would have wanted it any other way.

This fascinating documentary reveals that Vreeland (who died in 1989, aged 86) was an original: a dynamic woman with energy to spare and an infectious lust for life

What makes this such a joy to watch is not just the timeline of fashion highlights, but Vreeland's unique perspective on life.

The filmmakers have done a fine job corralling so many fantastic tales from Vreeland's life.

"Diana Vreeland: The Eye Has to Travel" is an intriguing portrait of a true original; you only wish the movie had half the color and verve of its subject.

A lively movie, and in the case of its appearance-obsessed subject, it feels right that all it does is skim the surface.

[Vreeland's] influence on twentieth-century culture was large, and it's celebrated here with affection, dedication and skill--but very little critical detachment.

Though unwilling to dig too deeply into what seems an imperfect private life, it still serves as a splendid introduction to a unique personality.

A poignant portrait of an inveterate iconoclast who couldn't help but push the envelope.

?Influencers Who Inspire? Interview with Jason Falls | Business 2 ...

This week?s ?Influencer Who Inspires? is Jason Falls of Social Media Explorer. We admire Jason for his honest approach to social media and we are avid readers of his very popular site, Social Media Explorer. Jason, who resides in Louisville, KY, is an author, keynote speaker and CEO of Social Media Explorer. He continues to be a name that surfaces at or near the top of conversations and lists of thought leaders and top thinkers in the emerging world of social media marketing.

How would you describe what you do for a living?

I do one primary thing in about three different ways. SME Digital, my agency, helps companies develop digital and social marketing strategies, execute them and measure/optimize results to drive business (unit sales, revenue or costs). My information products add the other two components: Explore Events helps anyone who wants to attend a two-day, intensive digital marketing strategy event and The Conversation Report analyzes online conversations and reports insights around specific industries (or clients for custom reports) to help businesses make smarter decisions about their social marketing. In a nutshell, ? Agency ? Events ? Research ? is what I do.

You recently tweeted to PR folks about how they approach you and that you are ?one of them? ? what prompted that and how do you handle being on both sides of the PR equation?

It was likely prompted by me being critical of public relations professionals, then having them attack me for it. Those that are easily put on the defensive about the PR craft tend to point fingers at me and infer that I don?t know PR, that I?m just a ?social media consultant.? But I spent 20 years as a PR and journalism professional before social media marketing ever happened. So I was probably saying, ?I am one. Thus, I?m qualified to point the finger a bit.? The way I handle it is by just trying to coach and teach and perhaps lead by example. ?Lots of public relations professionals still assume that ?spray and pray? and spamming people works best. I only hope to educate them that there might be a better way to approach outreach. Quality outreach is far better than quantity, and you can sleep at night knowing you?re not a spammer.

What?s next in PR now that social media is a given?

I think PR is the new journalism. With all the noise out there in the media world and declining numbers in usage and revenues in traditional mediums, public relations professionals (and current journalists who will become them) have the opportunity to become the media. Those that do so in compelling ways will have better public relations programs because they?ll become a direct conduit to their publics.

What?s the best social media campaign you?ve seen (besides your own) in 2012?

H&R Block?s Stache Act is by far the most compelling. To have a stoic, conservative brand like H&R Block get behind a silly tax incentive for mustached Americans and stage a Million Mustache March on Washington, etc., just gave the brand personality and showed that they could reach beyond the tried and true ?Let us do your taxes? messaging, in order to reach a new audience.

That, and Charmin?s Twitter account. Holy cripes, they?re funny.

How did you initially get your ?feet wet? in social media?

I spent 8-10 years blogging and exploring social networks and forums for personal entertainment. My old humor blog actually gained a bit of traction when I moved it to MySpace in about 2003. I learned how to build an audience, promote my content and connect influencers to what I was doing. Then in 2006, I started from scratch with an arsenal of experience in the business segment rather than the one focused on telling dirty jokes and made up tales of drunken debauchery. Heh.

Can you tell us a bit about your book ?No Bullshit Social Media? and why someone would want to purchase it?

Aside from the crafty title, the book?s real appeal is that it?s a blueprint for social media strategy. We walk you through the seven reasons (goals) your business might implement social media tactics and coach you through the process of developing a sound, strategic approach to using social that will drive measurable results.

As the Founder and CEO of Social Media Explorer, your approach with SME Digital involves Full Frontal ROI methodolgy, can you explain how this is unique to the industry?

The Full Frontal ROI methodology, which was developed by my partner, Nichole Kelly, essentially places social media marketing squarely in the crosshairs of business strategy. Everything we do is focused on real business metrics ? unit sales, revenues and costs ? rather than soft metrics. Sure, we can help you drive more fans and followers, but we know we?re ultimately judged on your bottom line and how social media and digital marketing contribute to it. So that?s what we focus on. It?s unique to the industry because most other social media agencies or digital marketing shops focus on the fluff metrics and Kumbaya of social media. We know it?s about business or it?s a hobby. And how many business owners out there consider what they spend time and money on to be a hobby?

What is next for you for the remainder of the year heading into 2013?

Two more Explore events (Orange County, Calif., this week; Portland (Ore.) in November), another The Conversation Report, this one on the restaurant industry, and continuing to help our clients kick ass. And I fully expect 2013 will be much of the same. That?s what we do.

Investing as a Group

On November 30, 2012

Investing on your own may prove difficult, especially if you don?t have the funds to make your investment dreams come to fruition. However, investing as a group, whether buying shares, investing in property or learning how to trade forex, gives you greater buying power and more potential to achieve successful returns.

Investment Clubs

(i) The Perks

An investment club is most likely the best option for new investors looking to invest their worth alongside others. Investment clubs are ideal for some investors, particularly because they have the ability to:

• Allow a greater buying power.
• Increase education for members and give them a chance to learn about the market.
• Give new members high-end, real-world experience in the marketplace.
• Bring in higher returns.
• Lower fees and expenses by splitting costs between all members.
• Give members the chance to share thoughts and ideas about investing.

(ii) The Downside?

However, one of the main drawbacks to joining an investment club is that many of these clubs can be operated by scam artists. These people set up the investment club with the sole purpose of enticing investors and then stealing all their money.

When searching for and joining an investing club, make sure that you do so by reputable means. Find out as much as you can about the club before you join and be wary of direct offers to join any clubs, even if the offer has been made by someone you trust.

A trustworthy club should have strong goals and investment strategies, solid rules and regulations, a set structure and should present the right paperwork and certifications.

Shared Goals and Values

It?s important in investing as a group that you all share common goals, ideals and values. If not, this can lead to much conflict within the group, and subsequently, certain members can try to take control. Regulations and rules should also be in place (particularly in regards to when to sell and buy commodities or shares), and any monetary values (whether fees or profits) should be equally shared amongst all the members.

Evaluate your long-term goals, strategies and approaches to investing and consider how your group can work together to leverage your investment success.

Plan Long-Term Investments

According to some sources, the trend of investment groups and clubs often follows the potential for high returns in a fluctuating market. When times are good, groups flourish; however, 12 months later, when prices have fallen, the groups fail and disband.

The key to investing successfully as a group is to select a group (or start a group and select members) who are serious investors committed to long-term goals.

Investors who are looking to make a profit within the next 1-2 years are probably not earnest about their investing. Instead, all members should be passionate about investing and keen to share knowledge about the marketplace, with a realistic vision of investing over a numberofyears.

Prolific Van Persie keeps United top of EPL

Associated Press Sports

updated 7:17 p.m. ET Nov. 28, 2012

LONDON (AP) - Robin van Persie preserved Manchester United's narrow lead in the Premier League with the quickest goal of the season, scoring after 32 seconds in a 1-0 victory over West Ham on Wednesday.

Defending champion Manchester City remained a point behind its neighbor with a 2-0 victory at Wigan on goals by Mario Balotelli and James Milner, but Rafa Benitez's tough start as interim Chelsea manager continued with a 0-0 home draw against Fulham.

The point at least lifted Chelsea into third place above West Bromwich Albion, which lost 3-1 at Swansea to end a four-match winning run in the league.

Tottenham climbed to fifth place by beating Liverpool 2-1, with Spurs winger Gareth Bale scoring at both ends, while Arsenal was held to a 1-1 tie at Everton after also taking the lead after less than a minute through Theo Walcott.

Stoke came from behind to beat Newcastle 2-1, a fourth straight loss for the visitors, while Mark Clattenburg - the referee at the center of recent racism accusations - made his return to the middle in Southampton's 1-1 draw at home to Norwich.

Benitez was greeted with roars of disapproval prior to his first match in charge - a 0-0 home draw with Man City on Sunday - but fans gave him a less hostile reception three days on.

Instead, there was a general feeling of apathy around Stamford Bridge which lingered throughout a listless encounter at Stamford Bridge, which Fulham edged.

Chelsea has clearly improved defensively under the pragmatic Benitez but its attacking spark that marked its bright start to the season has disappeared. Boos rang out at the final whistle, with Chelsea having created few clear-cut chances in front of watching owner Roman Abramovich.

"It's still a long way to go. We have to keep going. We'll have chances," Benitez said.

The Spaniard needs a slice of luck that Van Persie was granted at Old Trafford, with the Netherlands striker's shot looping up off James Collins and over stranded goalkeeper Jussi Jaaskelainen for his ninth goal of the campaign.

"We got a great start," said Ferguson, whose side has more often than not conceded first this season. "You hope to go on from a start like that and some of our football was very good, but we never quite finished them off."

For City, it was the complete opposite, starting sluggishly at Wigan but ending well to maintain its unbeaten start. The champions' goals came in the space of four minutes, with Balotelli marking his return to the starting lineup by burying a loose ball in the 69th.

Milner, a second-half substitute, wrapped up victory in the 72nd, only to go off injured before the final whistle with a hamstring problem.

MADRID (AP) - David Villa scored twice as Barcelona eased into the fifth round of the Copa del Rey with a 3-1 home win against Alaves to advance 4-1 on aggregate.

Alaves silenced the Camp Nou ahead of celebrations to mark its 113th birthday later this month by taking the lead when Borja Viguera headed Miquel "Miki" Martinez's long-range cross into the net in the 17th minute.

Adriano equalized in the 35th after beating a defender and then skillfully striking the ball low, beneath approaching goalkeeper Sergio Herrera.

Cristian Tello was felled in the 56th, earning a free kick that Villa converted for his 300th professional goal with a beautifully struck shot. Four minutes later, he added another from an assist by Tello.

Villa's goals steadied the home team and led to some fluid, fast-passing play, culminating in a shot just over the crossbar by Tello in the 68th and another inches wide by Villa a minute later.

Sevilla beat Espanyol 3-0 to advance 6-1 on aggregate. On Monday, Espanyol fired Mauricio Pochettino after four years in charge as coach. His replacement, Javier Aguirre, wasn't present to oversee the match.

Valencia, Levante, Atletico Madrid and Getafe also progressed after second legs in the round of 32.

FRANKFURT, Germany (AP) - Leader Bayern Munich labored to a 2-0 victory over 10-man Freiburg, while Bayer Leverkusen won 4-1 at Werder Bremen to move into second place in the Bundesliga.

Leverkusen has won five of its past six games and moved past defending champion Borussia Dortmund, which drew 1-1 at home against Fortuna Duesseldorf on Tuesday.

Leverkusen is 10 points behind Bayern, which earned the unofficial title of "autumn champion" with three matches to spare before the winter break, the earliest a team has achieved that distinction.

"There are still some matches to play, we want to extend our lead," said Bayern captain Philipp Lahm, who provided the pass for Vitaliy Tymoshchuk's goal in the 79th minute that secured victory.

Dortmund travels to Munich on Saturday for the featured match of the season, trailing Bayern by 11 points.

Stuttgart edged out last-place Augsburg 2-1 and Borussia Moenchengladbach beat Wolfsburg 2-0 in other matches Wednesday. Nuremberg beat Hoffenheim 4-2, the loss putting coach Markus Babbel under more pressure.

---

PARIS (AP) - Bafetimbi Gomis scored a hat trick as Lyon thrashed Marseille 4-1 to climb above Paris Saint-Germain to the top of the French league.

Steed Malbranque was the other scorer for the visitors before Loic Remy grabbed a 77th-minute consolation for Marseille, which had Rod Fanni dismissed late on.

Also, Montpellier and Lille progressed to the semifinals of the French League Cup by beating Nice 3-2 and Bastia 3-0, respectively. St. Etienne advanced to the last four on Tuesday by beating PSG on penalties.
