People used to think the network effect for MySpace and Friendster were insurmountable. I played around with Mastodon last night and I think it has some bad but not insurmountable ergonomic wrinkles, but I worry its decentralization will prevent it from ever becoming mainstream. Centralization makes it easier to deal with "bad" actors. Also Discovery is a huge problem: how do I discover people I know? How do content…
How do you even know the person you found is the person you wanted? Also if people flock to specific instances it will just keel over and die.
So, if you don't want to set up your own Mastodon instance under your domain, you can instead link your Mastodon account to your homepage running on a domain of your choice. It's not something I bother to do, because I'm nobody important, but if I was e.g. Taylor Swift or something, I could show that my Mastodon account was affiliated with www.taylorswift.com, and thus give you a pretty good idea that I'm actually the real deal.
From the Edit Profile page on Mastodon (v3.5.3):
> You can verify yourself as the owner of the links in your profile metadata. For that, the linked website must contain a link back to your Mastodon profile. The link back must have a rel="me" attribute. The text content of the link does not matter.
