Where? I have tried Bluesky a couple of times last year and it's minuscule compared to X. I just need to create a new account on X, then follow some popular account like ICML, ICLR, arXiv.stats, arXiv.ML and I'll get more research news than I could ever consume from the feed, the recommendation from related accounts often provide all the big releases from big labs, no following needed.

But I definitely notice a pretty significant portion of the academic CS community are beginning to materialize on bluesky. You can probably start with Nathan Lambert (natolambert) or Jeremy Howard's bsky and branch out from there. (They tend to be schelling points for open AI networks, simonw also, swyx would be if he started using bsky also.)
Paper skygest curates people you follow into a feed of posts mentioning papers if you want to cut down on other noise. (https://bsky.app/profile/paper-feed.bsky.social)
You can browse starter packs (https://github.com/stevendborrelli/bluesky-tech-starter-pack...) to get an idea of where the communities are forming. For instance, the macOS/iOS people I used to follow on twitter are posting more on bluesky. If steipete started posting there, that would be half my twitter/x feed anyway..
