Sorry, but I think this poll is kind of flawed. I know you mentioned that you're after primary use but you
also stated "
percentages that are hobbyists, professionals, etc.". So it's not just primary use, you also seem to conclude that someone is a hobbyist or a professional solely based on their primary use, and that's flawed reasoning.
I get paid to administrate / maintain several FreeBSD systems. This takes up several hours per day. But I also have a FreeBSD server park of my own which I also spend time on. Free time obviously, but that includes part of my vacations.
So.... primary use is definitely personal because that's where I spend most time on. Maybe I'm a little too geeky here but I include the time when my personal server is working hard throughout the night in building my ports, something I sometimes verify first thing in the morning.
But how does that suddenly nullify my professionalism?
