It's very interesting and I remember wishing for a long time that "two-server" protocols like email would start being made again. I already switched from Twitter to Mastodon last fall and don't regret that in the slightest. The community here seems nice so far, and the UI is simple and clean.

I've encountered some glitches like the live-update feature seemingly changing what post I'm viewing and mixing comments from the two posts. The instance I picked has had some performance issues and has gone down a couple times, but I'm chalking that up to a mass influx of users and activity (of which I'm very much a part).

I could use a browser extension that just adds an "open this post/community/user in my home instance" button when I'm browsing another instance so I can interact. Also some ability to put a link to e.g. a community in your post text that automatically sends you to that community via the instance you are viewing the post in.
