A topic that's notable but has little to discuss can get a lot of upvotes. A lot of the best stuff on this site has exactly that: lots of upvotes, little commentary, because the thing itself is notable. That's definitely not what happens on Meta threads. They usually get lots of votes then lets of repetitive spam-like comments about how ethically bankrupt Zuck or Meta or social media or algorithms or whatever are. A new comment on the behavior would be interesting, but most of the comments are basically just spam. I could probably get an LLM to generate most of them with ease. Perhaps the worst part is, even if there is novel analysis it's buried under an avalanche of "Zuck will grind you to dust" or whatever that gets repeated over and over again.

For a while that was okay, this kind of stuff was just contained in those threads. But it's started leaking out everywhere. Just spam like comments tangentially related to the topic that just bash a big company. That's the lowering of SNR that I find grating.

Oh, no, is someone being mean to the big company? :(

This is absolutely notable, and everyone should be concerned about it. Not so much the potential fakery, but the extreme deficiency of the actual product, which has had the GDP of a small country squandered on it. Like, there is a problem here, and it will have real-world fallout once the wheels fall off.
