count me as one of those.
Of all the popular social networks, SE has by far the highest percentage of annoying little pedants. They must recruit their users exclusively from dungeon masters of online D&D games and fired Reddit mods.
I actually almost posted something this week due to some weird segfaults I was having with a third-party library, but the github maintainer was active and responded in his issues list. So, crisis averted.
One of my funniest stories from my time there is how I once closed a question as off-topic (it was) and several years later googled to find one result which was the same question flagged by yours truly (it was still off-topic but the irony wasn't lost).
The Blender site gets ~50 questions a day. The Emacs site gets ~6 questions a day (with a total of 25k questions in eight and a half years, only about a fortnight of Stack Overflow).
It's just a completely different thing at those scales. It's the difference between a forum with maybe a few hundred people and Twitter.
So calling it "surprisingly bad" isn't fair. I still think it is surprisingly good.
StackOverflow is surprisingly bad and doesn’t really have good new questions, that is true. But the other sites are much more helpful. You just have to understand that it’s a QA site for nontrivial questions (i.e you cannot solve by just googling or reading the docs), not a forum for discussion
