Mashable founder Pete Cashmore makes a living throwing parties. Tumblr founder David Karp seems to get by on going to them, if only to make people say, "Why who's that fellow dressed so much like, Chuck Bass, and how can I join any website he's created?" This must explain why the two make such good dancing partners. But won't Iminlikewithyou founder Charles Forman get jealous? Write your own caption for this post and we'll use the best one as its new title. Friday's winner is bloggerman with "And in the end the stock you take is equal to the mess you make."

How many ex-Yahoo managers does it take to reproduce a classic Beatles album cover? From left to right: Salim Ismail, Chad Dickerson, Scott Gatz, and Bradley Horowitz. All four were, at some point, responsible for parts of Yahoo's advanced-products group, including the Brickhouse incubator in San Francisco. The band reunited last night at the 21st Amendment bar in San Francisco's South of Market district to bid Dickerson farewell; he is leaving Yahoo to become CTO of Etsy, the Brooklyn-based marketplace for hipster-friendly handicrafts one must nod politely about. Ismail is attending to Confabb, the startup he failed to sell before joining Yahoo; Gatz is now running GayCities, a queer-travel website; and Horowitz is now at Google.
