> First, you could talk to this programmer asking whether he/she would wish to integrate more closely with the other programmers' culture (perhaps he/she would like to but there's something preventing it, like shyness or other).

Wouldn't that seem a little forced, though? If shyness is the issue, I'm not sure what one could say to address that.

Isolation seems like a good idea. However I'm worried the rest of team would have their ego broken, or even that our startup like culture would shift to a more corporate structure. Having one or small amount of people in charge of one big thing would kill the bus factor; That would have to be accounted for somehow.
