I got access to the [Bluesky](https://blueskyweb.xyz) private beta (thanks [Ryan](https://snarfed.org)!) and have been kicking the iOS app's tyres. The app experience is basic but familiar. You can clearly see its Twitter roots. I was also pleased to be able to follow [Aaron's guide](https://aaronparecki.com/2023/03/07/3/bluesky-custom-domain) to using my personal domain as my handle.
The [AT Protocol](https://atproto.com) is also nicely designed. The federated social network world is certainly heating up.
