Lately, Stack Overflow has been a mixed blessing.

How it goes: I post a question(questions are rather specific, but technology stack is very common on SO)

I usually get one-two answers very quickly and maybe one more slightly delayed answer, all helpful but also rather generic. You definitely get the impression people are just point whoring.

After a day or two I end up accepting the closest answer, even if it is not that close.

Seems real experts have moved on or perhaps I am missing some trick in asking questions.

If this problem persists on their scaled out sites, I am not sure how much VC money will help them.
