I work 90% remotely. When I started this job, I came into the office everyday, a 40 minute commute. After about a month, my boss came up to me and said "Are you meeting someone here today? If not, what are you doing here?"

I actually like to go into the office from time to time, but there isn't any point when no one is there. I spend a lot of time at various clients' offices, and I notice a correlation: the more opposed to remote work a company is, the more meeting-driven it is. It is as if management feels like it needs to do something with all these bodies taking up space in the office. I see small to mid-size companies sucking up productivity with endless meetings.

That said, I think my company has lost a little bit of interactivity with the remote work force. I'm putting together a Google+ Hangout I call "Engineers' Office Hours". The idea is that if you aren't doing something billable, you hop in and offer help to someone stuck on a problem.
