For me, the strict requirements for posting questions help me to define the problem well, and after writing the question properly, I'd have the solution.

Early Stack Overflow as an amazing "rubber duck" (see "rubber duck debugging").

Unfortunately in recent years it became such a traumatizing experience to post a question there (even if you made a perfectly legit question you'd likely get downvoted and closed ... and god help you if you posted a question with an issue).

It completely changed from "I posted a question I can answer myself, and someone said so in the comments" to "I posted ANY question and everyone on the site teamed up to get rid of that question".
