First post here. Mostly to see if I can handle it.
@ruckawriter You can only start a conversation on other instances with an account there, but you can follow or reply to anyone on another instance just like you would on Twitter. If you use the tootdon app you can also add other instances to your homescreen. Just search for the instance and add it.
@ruckawriter And yeah, the instances thing is a bit confusing. I've got an account at mastodon.social and another at comicspace.masto.host . I kind of think of it a little bit like having multiple twitter accounts to follow different groups of people. I don't really juggling, honestly, and mostly just post from the mastodon.social account. And then periodically check the Federated feed at comicspace.masto.host to see what's up.
