Very pleased to see Panic (of Tweetbot fame) make a worthy successor for Mastodon. Priced at $2 per month or $15 for a year.
I picked up a copy last night. Mastodon as an ecosystem is still difficult to get started with, and the initial onboarding is a headfuck - once you follow a few people it starts feeling like the bird site of old.
Edit: I should note Panic have done a good job of cleaning up that initial onboarding/sign up experience.https://chanc.ee/20230125-panic-enters-the-mastodon-arena.html
