Only two days after we wrote about Tumblr's capitulation to advertising interests—by blasting porno Tumblrs out into the phantom zone—the company is already apologizing.

Since Yahoo! CEO Marissa Mayer began circling around Tumblr's billion dollar GIF vortex, we wondered what it'd do with the nasty stuff: the dog sex, the rape porn. Or even the more mild takes on fucking. Now we're starting to see: porn gets put where no one can find it.

If you use an iPhone or iPad to cruise Tumblr, change your login ASAP: the company just admitted a serious flaw in its iOS apps makes it easy for someone to steal your password out of thin air.

Only three short, sweet years ago, David Karp was just another dreamy eyed dropout sitting atop a billion dollar idea. He wore a lot of plaid. He told the L.A. Times that the concept of advertising "really turns our stomachs." Today, he's on the beach, saying the best part of Vogue is the ads. David.

Earlier today an anonymous founder created a Tumblr called My Startup Has 30 Days to Live, chronicling the advice from investors that left him unable to make payroll. How does a once profitable and bootstrapped company morph into the startup walking dead? By following the contemporary formula for startup riches: boosterish article in the tech press, join a top accelerator, give good deck on Demo Day, cash the VCs checks, crush it . . . you're the next Dropbox.

The gilded dust has settled across Cannes after last week's advertising Hajj, and by all indications, Tumblr's party was a hit! Drinks, palm trees, etc. But we weren't invited, and neither were you, so here's what it would've been like to attend Karp's fabulous French bar tab.

David Karp, the proud new owner of generational wealth (despite 2012 revenues of less than $5 million), is in France this week making some new best amis! At the Cannes Lion International Festival of Creativity—a posh back-patting bonanza designed to make advertisers feel special—Karp took the main stage, only to throw his employees under the bus:

Further proof from Jakob Lodwick that you don't necessarily have to have a good idea to make money in tech. Two of the fameballer's investments have been acquired this year: Tumblr and now MakerBot, where, until recently, he described himself on his blog as a "founding investor." Depending on how many shares he held, it should be enough to keep Elepath's ball pool filled.

Tumblr brought Mark Coatney aboard from Newsweek to bolster the site's editorial side—"to show how [Tumblr] can be key to connecting journalists and readers." Three years (and a Yahoo acquisition) later, and another early employee is gone. That's two in only a few weeks.

When Yahoo's billion dollar Tumblr pickup was nothing more than coquettish tech talk, we wondered if a new owner would start enforcing the site's own rules. You know, shutting down pages about underaged girls and glorified anorexia. It looks like it's starting. Slowly.

Jacob Bijani joined Tumblr as one of its original, most formative employees (and its first designer/product engineer) back in 2008—when a $1.1 billion Yahoo buyout was unfathomable. Now he's leaving.

After high school dropout David Karp turned Tumblr into a $250 million payout from Yahoo, lots of parents around the world are probably looking to duplicate the recipe. Here's part of it: let your kid have and do whatever they want.

Starting today, you'll see things like promotional GIFs for Denny's in your web Tumblr feed (just like you had before via mobile), according to the company's staff blog. "These posts will simply blend in with the posts from the blogs you follow," says Tumblr, except that advert posts will be stamped with a dollar sign with lines shooting out of it.

There are first world problems and then there's the troubling "rich-person management gap" currently harshing one newly-minted tech millionaire's mellow. Break out the Stradivarius of tiny violins.

Cloying, GIF-happy, nostalgic, attention span devoid—this woman-as-website impression could only be better if she, well, did some really horrible things! But it's otherwise perfect.

Yahoo CEO Marissa Mayer is plowing through a media tour with her newly adopted internet son David Karp. On everyone's mind is how Tumblr will reconcile its vast collection of rape porn GIFs with tween-friendly advertising—and the duo doesn't have much of an answer.

We all know about Marco Arment's "not yacht rich" fortunes from Yahoo's microblog bailout, but what about the venture moneybags? How did the investors get in return for writing checks? A lot.

Insecure code-slinger Marco Arment was an original employee at Tumblr, when it was just two dudes in a room. He wrote a nostalgic little post yesterday about the company's rise to Yahoo's pocketbook, with one important conclusion: he's rich too. OK? Very rich. Not yacht rich, but rich. OK?

If you enjoy Tumblr's extensive selection of rape fantasy, underage girls, and women having sex with a variety of fauna, good news: Marissa Mayer just said she's keeping Tumblr NSFW.
