I've been telecommuting for almost six years now and the thought of going back to an office is terrifying. I would end spending 2+ hours in traffic, be separated from the things that matter to me most (wife, 2yro, two German shepherds) that also provide a bit of refresher when things aren't going well. Good luck playing ball with your dog in an office.
Having been at an all-telecommute shop i can say that we ended up doing far more work than most teams. 10pm email conversations with the CEO were normal.
Easy, get up, do a bit of work. Have breakfast, spend it with the family. Do some more work. Play with dog. More work, then lunch. Another task, then break time with the boy. A bit more work, then dinner. Family time, kid/wife goto bed, stay up and do a bit more work.
I found it far easier to do that, than to veg out in the office when I needed a break to go out, see the sky, walk around, breathe, etc.
Also, this was fairly early on, sphere was a new company and we were having growing pains. And its not like it was a nighlty thing, more along the lines of often enough to not be weird, but it wasn't often.
Also, before we were quasi-detelecommuted (meaning hires in NYC that went to the office) when something broke, everyone would pitch into fix regardless of hour. After the original peeps (well, most of us) left, the replacements (in the office) had an office mentality. That is, anything that happened after hours wasn't their problem.
Maybe that works better for them, but not for me. Doing things my way got more of my awake/alert time for actually doing things, and the flexibility it imparted helped keep me sane. Offices and rigid schedules drive me batshit insane.
