More importantly, talk about stuff besides Reddit!
I tried using Voat 6(?) years ago when there was a similar (but smaller-scale) protest. The fact that a lot of Voat users were those chased out of hate subs was part of the problem, but the other part of the problem was that half the content was "look how much better we are than reddit".
Discussion about reddit is fine (it is still a big site), but we need our own content too.
the community here is doing a decent job - I think it's just whether we can all continue to engage actively here (and not get up to shenanigans like defederating from everyone else ahem)
