It has rather ensured that I never made any effort to contribute to that community. I do still use SO answers if Google or DDG happen to provide me with a link to one that answers my question, which in fairness is quite often, even most of the time. But when so many of those clearly helpful answers (often answering my own question to the letter), are downvoted/locked over some matter of bureaucratic principle or the opinion of a nameless moderator, it makes it abundantly clear that any contribution I might occasionally wish to proffer will be unwelcome, and any question I ask is as like to be met with censure as actual assistance.
Actually participating in SO seems these days to be about as fruitless an endeavor as editing Wikipedia was.
