Absolutely not.

1) This is a people problem, not a site problem. Technology professionals do not have a good track record of being socialized and generally well-adjusted, and for every singular tech professional who is, there are a dozen horrid maladjusted ones who are unfortunately successful and find themselves with power they aren't mature enough to have.

2) StackOverflow is still a treasure trove of information and a place anyone can go and ask questions about even niche and deprecated technology. Just recently asked a question about InnoSetup on StackOverflow and got a great response from possibly the expert fellow on InnoSetup.

Having an "invested community" requires an inordinate amount of effort from a tiny handful of founders for uncertain reward.
