This is very sensible point you have made. I said something similar in another thread that not everyone is looking for in-person watercooler conversation, office politics, promotions / raise and so on. Some people like me are fine with finishing up assigned work, attend phone/webex meetings and be done with it. It is usually run-of-the-mill n-tier business application for next requirement for last 10 years. By not going to office the only thing I am missing in 2 hr commute and crowded elevators and rest rooms.
