So how did high school dropout David Karp respond to the news Yahoo had just bought his baby Tumblr for a billion in cash? With a glowing, fist pumping letter signed “fuck yeah!” BTW, he started the company just 6 years ago. What were you doing in 2007? Setting up your billion dollar windfall? Don’t worry, I’m sure he’s a total dork, except for the part where he’s handsome, seems pretty funny and has a cute girlfriend. Dick.
