Low quality article aside, Threads also had a major spike in usage that quickly dropped off. I could be wrong, but I’m going to guess Bluesky will be the same. They don’t seem to offer anything new/different other than moderation, which I’m not convinced is enough to shift momentum from x to bluesky
If you want to find your colleauges' posts, if you want to find high quality information, if you want good links to long articles, X is no longer the place to be.
If you want to have click-bait and rage-bait or lots of right-wing politics, X will cater to your needs. But it won't cater to somebody that's trying to get to highly-curated high-signal information networks that Twitter allowed in the past. That's all been actively destroyed, with great intention.
