Bluesky, a decentralized Twitter-like social network, is pausing new signups “temporarily” to try and resolve performance issues it’s been experiencing after Twitter introduced limits on the amount of tweets you can see in a day. Even though you still need an invite code to be able to join Bluesky, it seems that the influx of new users has been a problem.
Irrespective of the popular success which Bluesky / Mastodon may receive, I am simply glad that enough platforms exist for anyone to seek refuge in if the rapacity by these giants becomes the norm.
No. It's decentralized like the Fediverse, but it doesn't use ActivityPub. I think there are some 3rd party developers working on an ActivityPub-Bluesky bridge, but nothing concrete yet.
It's unfortunate that this drop in replacement isn't in the fediverse though. Bluesky's success isn't technical (yet), it is better marketing and connections with VIP users.
