My general impression of the "opinion/advice" questions is that they're mainly bots talking to bots, with occasional "organic" marketing paragraphs promoting some tool slipped in. They're also often a particularly tedious form of AI answer since the nature of the question means they end up waffling around the subject in vague platitudes with nothing really concrete to say.

I'm not sure if that's the inherent nature of the subject matter, or just the fact they're much less heavily moderated.

(Ironically, Reddit -- which I think is the discussion-type model that you're trying to go for -- does actually seem to have more human-written content in a lot of the programming sub-reddits, and people are often fairly good at calling out the more egregious AI slop.)

Either way, my immediate impression whenever I open one of the discussion-type questions on Stack Overflow is usually "there's nothing that's worth my time reading".
