Although I'm a little late to Mastodon, I'm very enthusiastic about the ideas built into it (especially several of the technologies, which I previously worked on). Having decent clients is really helpful for adoption and growth, and Amaroq is surprisingly well done considering its relative immaturity.

Mastadon seems like its what slack was last year (in the community aspect) yet decentralized. Interesting to see where it goes.
