If you're looking for accounts to follow, you might like to check out my other account FediFollows:
➡️ @FediFollows
It regularly posts themed lists of good accounts to follow, and it also has a website with thousands of recommended accounts sorted into topics:
To follow an account listed on the website, copy-paste the "Fediverse address" on its listing into the search box in Mastodon and then click "Follow".
