I don't like working in solitude myself. I'm a social person, and I need other people to bounce off of.

I'm not the only one, either. I was trying to recruit an old colleague (and I'm not done trying to recruit him!), and his biggest concern about going to an early startup was the lack of a team to work with. He's one of the nicest and most easygoing people I know, and a natural leader. I'd love to have him leading a team of developers for me. But first, I'd have to get him a team.
