>It might be a nice idea for Mastodon advocates to create general topic instances, that may feel more approachable for newcomers.

Yeah, the instance names are often quite silly, but there's silly people on there. I mean 3000 variations of "mastodonUKsocial.com" or something wouldn't really tell you all that much more. If you don't want to go to mastodon.social, the biggest english language instance, octodon.social is a good, smaller (~11k users) general instance with a good vibe. Fwiw i think a lot of people use twitter to follow 'their kind of people' (lgbt groups, open source fans, music people) and this codifies those groups a bit more into proper instances/servers/communities, while of course allowing you to follow other people.
