Stars: they're just like us! Getting chastised by photo sharing apps for posting supposedly inappropriate content.

Madonna posted a letter to her Instagram today that she received from the Instagram team. The letter warns her that some of her photos have violated the company's community guidelines, and reminds her to abide by Instagram's rules, such as not posting nudity or illegal content. It advises her to delete the offending content or else her account may be shut down.

It's unclear which photos violated the community guidelines. There's one showing Madonna's buttcheek but that's completely G-rated compared to other stuff on Instagram.

It is kind of refreshing to see celebs held to the same standard as regular users, but also--it's Madonna. Obviously, Madge herself scoffs at the idea of a startup trying to stifle her creative license. After posting an image of the letter without comment, all of her fans have commented things along the lines of, "UM H E L L O IT'S MADONNA."

Mobli, a photo and video startup that's no stranger to celebrity users (it counts Leo DiCaprio and Tobey McGuire as backers), released its own response to Instagram's celeb faux pas.

Well, that's one way to go after celebrity users.

Congress Fail Whale (Photo: blogspot.com)

API Rate Limit Exceeded Back in April of 2010, the Library of Congress promised to add every tweet up to that date to its famous archives. But like anyone following too many people at once, it's just caused one big mess. The library now has an archive of approximately 170 billion tweets totaling to a compressed 133.2 terabytes. Now the librarians of Congress are planning to work with Gnip, the company currently organizing all of the data, to develop a plan for archiving all of the tweets.

Apparently there have already been more than 400 access requests to the Twitter archives from researches doing work on citizen journalism and political communications. Someone needs to teach the librarians how to make lists as soon as humanly possible.

Schools Get Cash The New York State Energy Research and Development Authority (NYSERDA) has just pumped a bunch of cash into New York's tech universities. It has awarded a total of $15 million to Columbia University, the Polytechnic Institute of New York University and High Tech Rochester to create three Proof-of-Concept Centers dedicated to helping inventors and scientists turn their high-tech, clean-energy ideas into successful businesses. Columbia will form a new accelerator, several upstate schools will work together on a new development center, and NYU-Poly will work with CUNY to create PowerBridge, an applied science research institute that focuses on challenges specific to an urban environment.

Drop The Ball, Up The Traffic The customized mobile site publisher Onswipe had lots of reasons to pop champagne on New Year's Eve. The company says that it has reached 44 million unique visitors in total for 2012 and now is reaching more than 10 million monthly active uniques on iOS devices. The publisher also saw a huge bump in traffic after people opened their gifts on Christmas morning. Most notably, in the two days after the holiday, total unique visits on its sites jumped 22 percent and Kindle Fire unique visitors increased 75 percent.

Get Glasses, Give Glasses Diane von Furstenberg is teaming up with the insurance company VSP Vision Care to run a contest on Pinterest to help benefit the NYC Mission Society. Every time an image gets repinned from the VSP Pinterest Board, a gift certificate for an eye exam and glasses will be donated to the New York City Mission Society. These repinners are in luck too--when a user repins that image, they are automatically qualified to win a pair of DVF sunglasses and a $500 DVF.com gift certificate.

Move, Drop, Shake Unpakt, the site that lets you compare movers, continued its “Innovators on the Move” series. It features tech entrepreneurs reflecting on recent moves in their lives. This week's video features VHX founders Casey Pugh and Jamie Wilkinson talking about the move to its first offices in Brooklyn.

Baby You're A Firework (Filter) The favorite photo sharing app of the Williams sisters, Mobli, just celebrated 2013 in the best way they know how--by adding two new filters to its app. Both of them are New Year's Eve themed. One has a fireworks overlay, while the other has "2013" glittering in gold. Siiiick.

Live Like 'Countdown' Just last month, Gojee was the site to go to for recipes based on what's in your pantry. But it's recently launched a slew of fashion verticals which include landing pages for lingerie, heels, dresses, jewelry and handbags. The recipe sites are still up, so there's no need to panic about your dinner just yet. This makes living your best Beyonce life ("All up in the kitchen in my heels, dinner time") all that much more possible.

More Style Buying Speaking of buying clothes based off the pretty images you find on Tumblr and Pinterest, there's now StyleSays -- a new fashion image sharing community that connects users’ favorite style images to purchasable content. It tags pictures of pretty outfits with links to purchasable items. Some might be the exact product and it could give you an affordable alternative.

AT&T Sucks If one of your New Year's resolutions is to ditch your phone provider once and for all, consider making a switch to T-Mobile. The company is now touting the results of its $4 billion commitment to improving service and says its reception in New York is better than ever. Neville Ray, the CTO for T-Mobile, said in a blog post that NYC customers "can also bring their unlocked AT&T smartphones to T-Mobile and experience a significant speed boost on our network with most devices, while also saving up to $50/month compared to AT&T."

Old dog learning new tricks, etc. Bluefin Labs, the social TV analytics company for advertisers, just added an important employee to its team. Scott Grunther, a former Nielsen executive, is joining the Bluefin team in 2013 as a senior vice president. He will also be the general manager of media products out of the company’s New York office. He's been in the industry for 20 years.

NYC-based Mobli already has a cadre of celebrity investors, but now it can claim an impressive infusion of cash as a new bragging right. The photo and video startup, backed by celebs like Leo DiCaprio, Tobey Maguire, Serena Williams and Lance Armstrong, announced today that it has raised $22 million in Series B funding.

Twenty million of the new round comes from Kazakhstani businessman Kenges Rakishev, with the remaining $2 million kicked in by previous investors.

"This latest injection of capital will support the continued innovation and development required to become the premier destination for mobile photo and video sharing," Mobli CEO Moshe Hogeg said in a press release. The company intends to use the money to expand its audience base.

Two months ago, Mobli announced that it had reached three million active users. A spokesperson assured us that, since that milestone, the company has seen significant growth. The number of photos shared, for example, has tripled.

As for those celebrity investors, they don't seem to be using the product all that often. Mr. DiCaprio hasn't shared anything on the site in two months; Mr. Maguire hasn't used it in three. Maybe $22 million will help convince them to hop back on the bandwagon. Mr. Armstrong, who seems to use the service quite frequently, might be able to give them some pointers.

Two posts and counting!

Silicon Alley syndicates aren't the only folks who like to invest with their friends. The New York Post reports that Lance Armstrong has taken a stake in Mobli, the New York-based social networking startup that raised $4 million from Leonardo DiCaprio and other "high-profile" investors in October.

The seven-time Tour de France winner, who is already posting photos to the site, "will use his fame and legendary drive to help the company gain traction in the competitive field of mobile apps," the paper says. Hey if @mrskutcher can drive design sales, why shouldn't a celebrity cyclist help with your mobile strat.

Mobli's spokeswoman tells Bloomberg than Mr. Armstrong's stake is smaller than Mr. DiCaprio's and promised that a formal announcement would be coming in a couple days. Along with the investment, Bill Stapleton, Mr. Armstrong’s agent, will join Mobli’s board of advisers. Can a retroactive cofounder title for a starlet's makeup artist be far behind?

Moshiko Hogeg, Mobli's founder, tells the Post that he became interested in working with Mr. Armstrong because the sports star was among the first to gain 1 million Twitter followers.

I'm the king of the world Startupland!

Startup fever just hit the Hollywood A-list. Mobli, a visual social platform, announced today that Leonardo DiCaprio was one of the "high profile investors" behind its $4 million seed round.

Mr. DiCaprio, who ranks no. 71 on Forbes latest list of The Celebrity 100 for commanding $28 million a film, will also be taking on an advisory role at Mobli.

As Mashable's Sarah Kessler reports, aside from the ability to follow users/locations/topics and a tagging feature that automatically adds the location of the image or an event in the vicinity, Mobli's big distinguishing factor is its celebrity connections.

"Well-known users like Paris Hilton and David Arquette have helped user acquisition — and now that Mobli is being more specific about what kind of investors stand behind it, it’s easier to understand how the startup might have gained such influential users.

DiCaprio uses the platform, but sparingly. He’s posted seven times, but managed to collect more than 8,000 followers along the way. The Leonardo DiCaprio Foundation, an environmental organization, has posted 24 times."

Lukas Haas, a fixture in Mr. DiCaprio's entourage, appears to be a more frequent Mobli user.

As Mashable also points out, celebrity traffic spikes, like the wave of Beliebers who followed Justin Beiber's first Instagram, or even @aplusk's Twitter effect, aren't necessarily a bad thing.

Maybe it's time for CAA to set up that Silicon Valley office they were sniffing around. And if the whole thing bursts, hey at least they'll have a lead on the movie rights.
