Oh, yes, this -- I completely agree. I don't want people to feel like they have to constantly walk on eggshells, but a certain amount of awareness of who might be reading something and how it might affect them is good for everyone. It can be a tricky balance, though, so I guess there will always be slip-ups even if we're trying.

I try to remember also that even though I'm in a small fandom, I don't actually know everyone who's reading stuff. People might be poking around, trying to decide whether to join in and how (this was me, several months ago), and I want to either encourage more people to join the merriment or at least not discourage them. Don't really want to ruin the day of any committed lurkers, either, ideally.
