one thing I think that might be lost on newcomers is the fact that this past week has been BANANAS for everyone who's been on the site for years, and if you feel like people are being snippy or pushy about social norms, that's probably why.
on a normal week when people talk about "hey please CW that" or "please don't spam your tweets here with a crossposter" or whatever they're more likely to do so patiently and explain the reasoning behind why we do things that way but on a day like today things are more likely to get a little snippy or terse.
don't take it personally! the old timers are trying to maintain social norms in the face of a flood of change, and they're worn out. keep that in mind if you think to yourself "hm; this place doesn't seem that friendly". give it some time to get back to normal before you bounce.
@technomancy why don't people like crossposters?
