One of the best things about Bluesky is that it's exciting. Yes, Mastodon has all the features, but the problem is that's around 90% of the features it will ever have. Bluesky is really new and already has unique features like feeds and labelers, and that is just the beginning
I wonder if it is possible to build a Mastodon instance on AT Proto? Like, it stores posts and other data on a PDS, and basically translates ActivityPub requests to PDS requests. Seems like an interesting idea
