New user sign up is a bit wonky. It asked for an email, login and password, then it's asking for a bsky sign-in too? This seems a little weird.
(Minor nit: for some reason, Google didn't auto-suggest a strong password for the password field.)
Then I got to the screen where it asks for full read-write access to my PDS and stopped there. It's kind of a lot to ask! I believe this is Bluesky's fault, but I don't think I can really use third-party bluesky apps until they implement finer-grained permissions.
only reason I backed away from it is that when the bsky team had a big "fuck the users" moment, the user purporting to be the tangled founder was happy to cheer them on. so between having to use AT proto, and assuming that the tangled dev doesn't really disagree with bsky's "fuck the users" sentiment, I moved on. but, obviously, whiny moral grandstanding is irrelevant to whether or not someone made a good product. if you've got a use for it, I'd certainly recommend giving it a try!
