@danielmrose I don’t think it’s a barrier on the Micro.blog side. They’re quite open with their API and there are plenty of third-party apps (I’m using Gluon right now!). But it’s different than regular Mastodon, and it would take significant customization on the Mastodon app’s side to support its “flavor” of ActivityPub and features. For not a huge market, that’s probably a tough sell.
I’m only half in right now (main blog still over at Blot) but am seriously contemplating going all MB all the time. 🙂
