What Does Garry Tan Miss About Being a Founder at Posterous?

Kyle Tibbitts introduces Garry Tan as an early employee at Palantir and the founder of Posterous, the company Twitter acquired. Tan now invests with his cofounder Alexis. What he misses about building is ordinary. A real user emails that the software is broken or does not do what they need. He opens the code, fixes it, ships, and replies within an hour that it is fixed. He says that loop is the part many founders cannot stand, and that it is the part he wants back. Some of his closest professional friends came from those exchanges, and they still follow one another's work.
