Tumblr's Mr. Karp (Photo: wikipedia.org)

PartyHat.GIF Tumblr just passed a huge traffic benchmark by finally reaching 170 million global users a month. It's now the ninth most visited site in the U.S., according to Quantcast. David Karp took to the Tumblr Staff site to congratulate his users and say, "You guys have earned an audience bigger than the biggest TV networks, and you continue to make some of the most thought provoking, insightful, inspiring, funny, diverse, and compelling content being created today."

Young Money Also worth noting is that Tiffany & Co launched their official Tumblr today. It's called From Out Of The Blue. The blog contains a couple pictures of necklaces containing an unfathomable number of diamonds and a promotional video that would make any tween ask their parents for a diamond tiara. That's what Tiffany is going for, right?

Put Your Skills To Good Use The New York tech community organizing group, NY Tech Responds, is putting on a grouping of events dedicated to helping Hurricane Sandy relief efforts. On December 1st and 2nd, they'll be having a talk called the Sandy Relief Agency Conference, a hackathon, and a reception to kick off their Sandy fundraising campaign. Registration for the hackathon is now open and you can get tons of more information on their website. Use your skills to help those in need!

Custom Giving Is Good Makeably, a marketplace for custom goods started by two ex-Googlers, has just launched a campaign with New York Cares called Make for Good. Kids from the Bronx have drawn their ideal Christmas wish and when a Makeably user sponsors the project, it gets made by one of the site's custom makers. Since its launch, the project now has around 150 makers helping out in 15 countries. Buyers no longer need an access code to help out.

Finna Reschedule That Startup Weekend's plans to team up with the FinTech Innovation Lab and the NYC FinTech Startups meetup for the first-ever FinTech Startup Weekend were squashed by Hurricane Sandy. But have no fear! The event has now been rescheduled for December 7 to 9 at Alley NYC. Throughout the weekend, there will be mentors, including VCs, lawyers and designers, stopping by to give teams advice on what they’re doing.

Nick Gavronsky, an OpenFin employee who helps run Startup Weekend with Frank Denbow, told Betabeat earlier this month that FinTech weekend is “not really like a hackathon, it’s more for first-time people” who want to start building something.

More Exploring Now Possible The gamified city exploration site, Stray Boots, announced today that it completed a $2 million Series A funding round. The round was led by Milestone Venture Partners and joined by Correlation Ventures, Great Oaks, and several angel investors. This is Stray Boots’ first venture capital raise.

Cabs Are Expensive Apparently a lot of people don't feel like spending money to get to the airport to see their families. Shairporter, the site that lets you split the price of a cab to get to the airport, told Betabeat that its user base grew 70% over Thanksgiving weekend. Founder and CEO Winston Wu told Betabeat that the company is still in continuing discussions with NYU dorms for their next big push for the holidays in December. The company also gave away free cab rides to NYU students who shared their page on Facebook on Thanksgiving.

Vamos De Compras Bêmbele, Latin America’s new men's and women's e-commerce site, went live yesterday. The company is a joint venture between New York City based private equity firm PanAmerican Capital and two other significant organizations in the Latin American region. CEO Dean Schaffer was quoted in a press release sent to Betabeat as saying, "Bêmbele takes care of every aspect of the logistics process for our customers –including duties, import taxes, and shipping expenses– and delivers an order directly to their door at no additional cost.”

The latest West Coast outfit to open up an outpost here in the chaotic environs of New York City: social commerce platform Polyvore. Their new neighborhood? Naturally it's Soho, that downtown anthill swarming with fashionistas. While the company has had employees stationed here for years, the new office finally gives them a proper home.

Polyvore, which makes it easy for members to create those inspiration board-like collages so beloved by fashion bloggers and also to purchase whatever happens to be featured in those collages, just topped 17 million uniques per month. Over the last year the company has been working more closely with brands, including hosting its first fashion show in February, featuring FIT alums.

Cofounder Pasha Sadri told Betabeat via email that, "Being in close proximity to the fashion powerhouses of New York was a natural next step" for the company.

However, don't make the mistake of thinking they're uprooting their technical team just yet. "Being in New York will hopefully allow us to lay down our roots and further increase our participation in the fashion industry," Mr. Sadri told us, adding that the office will be a "hub for advertising sales and partnerships with the fashion industry." He expects to hire a Vice President of Sales, who will be based here.

"Many of the world's greatest brands are based in New York, but a lot of the innovation in advertising and marketing is happening in Silicon Valley," Mr. Sadri said. "Polyvore's approach of combining social commerce and advertising is unique and we're excited to share it with New York."

At the moment the company has eight New York employees, but the company is growing fast enough that number is likely to increase.

The company even got an official hello from one-man tech welcome-wagon, Mayor Bloomberg. Tucked into Polyvore's announcement was this bit from Hizzoner:

"By opening an office here, Polyvore is joining the growing group of tech companies who recognize that the benefits of being in New York City are irresistible, regardless of where a startup began."

Hear that, everyone on the West Coast? New York will have even those companies that aren't locally grown.

Polyvore's investors include Benchmark Capital, Matrix Partners, DAG Ventures, Goldman Sachs, and Vivi Nevo.

A shot from the Stylecaster/Etsy photoshoot in DUMBO.

Stylecaster, the community-driven fashion platform, has teamed up with the Internet's answer to Zooey Deschanel, Etsy, to help bring accessible fashion to the masses. The two NYC-based companies collaborated on a photoshoot near Etsy's HQ at Dewey's Candy Store in painfully hip Dumbo. It's a powerful collision of New York startups and style, so be sure to don your best shades, lest you be blinded by the breathtaking twee-ness of it all.

"In order to direct the stylish shopper to entrepreneurial e-commerce & crafts, as opposed to unattainable runway fashion, StyleCaster's team of expert editors curated some of Etsy's finest to style its most recent photo shoot," said Meghan Cross, Stylecaster's director of communications, in an email. "In partnership with Etsy, StyleCaster is pushing the boundaries of high-fashion styling, supporting the incredible talent that first flourishes online - before the runway."

Stylecaster is also teaming up with Polyvore, an outfit and inspiration community, to help curate some of their best boards. The first page of the Polyvore editorial features New York style icon and Pinterest poster girl Olivia Palermo, along with an adorable pastel bike posed near a flower stand, so the whole spread should have a million pins by the time we post this.

Check out two exclusive photos from the Stylecaster/Etsy photoshoot below.
