If one of Reddits big goals in all this is to sell actually useful information on a broad variety of topics for training LLMs (I think they’ve basically said as much), then I’m not sure that only being able to prop up a few meme and cute animal subreddits is that much of a win.

It’s the long tail of niche subreddits where almost all the content that keeps Reddit at the top of SEO rankings and makes them interesting for training AI lives.
