My experience with the late SO was, that the original question used to be ten years old and filled with responses that were no longer relevant to the current state.

What amazes me is that an LLM can actually make sense out of all this crappy training data and often produces meaningful answers. (maybe that's a sign that we already have AGI)

You'd also get people downvoting completely valid rule abiding questions, and the site heavily punished being downvoted. So you'd get hit with a stick repeatedly for trying to engage with the site, it's no wonder everyone left as soon as there was an alternative.
