The last project I worked on, the company insisted I be on site. When I got there, nobody talked to me in real life for six months. If everyone is on IRC and using a ticket tracker, bug tracker, github, status blogs, email, Skype, iChat etc, I'm not sure what the point of being on-site is, other than organizational inertia.
