Yeah, the HD2 community has generally been pretty awesome. I've got something like 270 hours logged at this point, almost exclusively with randoms through quickplay, and I think I've only had like 5 people who were truly trying to grief anybody else in that time. There's a good handful of people who overreact to getting TK'd, but generally people take it in stride.

It was a bit worse shortly after release, though I think that was largely due to people not really "getting" what the game was yet (things like kicking people before extract to "steal" their samples, etc). Now that people have a general understanding of how the game works and what to expect when playing, there seems to be a lot less hostility overall, at least in the lobbies I've been playing in.
