SHS is definitely dying, though I pop in over there sometimes still. I think, honestly, that they didn't appropriately mod their community and then they lost it. You have to have a very clear sense of what's allowed and what isn't and when you step in and when you don't because otherwise either trolls end up poking everyone or the moderation feels uneven and unfair and either way people leave. I think people are more likely to stay in a community where they don't agree with some of the rules, but they're clear and enforced really evenly.
SEA makes me a little crazy. It's a huge, diverse group and it's mostly well-modded and I know so many people who are gung ho for it, but I always end up feeling annoyed after reading it. I'm still on there, but I rarely read it these days and I took it out of my FB feed.
I haven't read any of my yahoogroups in ages other than the really local ones.
I hang out on the Brave Writer Lifestyle FB group. And I have a few other FB groups I read.
Honestly, this forum is one of the best places, at least to me. I find that what unites people here is a real appreciation of and thoughtfulness about education. People here really believe in learning, even if we have different religions, parenting styles, and even methods of teaching.
On another group I read, there was a mom not long ago who said how her ds was cheating on his algebra work. They were using TT and he kept plugging the algebra problems into those online solvers. Well, the majority of respondents said that was CLEVER and good for him for figuring out a smart way to do his work. I nearly screamed through the computer at them. So the moral is why spend too much time anywhere but here because you'd better believe that the WTM board doesn't have parents who would put up with that nonsense.
