What's a Tumblr Meetup? It's when a bunch of kids who look like a tumblr feed meet up, right? Wednesday's open bar evening at the TriBeCa Grand met Tumblr developers and users, plus pop socialites and a juicy slice of New York's fashion crowd. Cute guests of Nicola Formichetti's from all over got together and wore nametags (so you can follow, bb!), ate grilled cheeses, and toasted Diesel's new Tumblr, brought to you by the brand new creative director, Nicola Formichetti.
