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.<p>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.<p>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.
