I guess SO was quite useful for providing a lot of training material for technical question answering for LLMs? I don’t think they got compensated for it so that is a bit sad.
In terms of my use, most questions and answers either were low quality, the question was a bit off of what you really wanted to know, or if it was a problem that required discussion or opinions, a ”real” hobbyist forum was better.
While at some point I felt like I (tried to) look up everything from SO, I now basically never use it anymore, but thanks for all the fish!
