Mastodon reminds me of Geocities and the early web. I mean that in a very positive way; it brings people together with other like-minded folk to share an online experience in a similar manner to the way Geocities did for people who wanted to publish their ideas in the 90s/00s. The expectation that permeates the birdsite that you should present yourself as a professional, or as funny, or socially adept, or whatever is missing here, and that's a really good thing.
