The One-Person Product
I know very little about David Karp. But after reading this, I'm a bit surprised that he decided to sell Tumblr.The way Marco talks about David's disinterest in money, and his singular obsession with Tumblr, made me think he wouldn't even consider selling it to someone else.I'd be curious to hear his reasons for selling, as oppose to doing a strategic investment like Facebook did with Microsoft at one point.
