If you know someone who wants to make the switch, here are some resources to help them:
How does Mastodon work?
Mastodon info incl. mobile apps
Twitter-style interface for Mastodon
Mastodon Crossposting service
(M -> T currently blocked by Twitter, but T -> M works)
I've also done a thread listing these and more resources on Twitter.

@switchingsocial moa.party does Mastodon to Twitter just fine it seems
@switchingsocial IFTTT can be a great tool for cross posting as well. Mastodon exposes an RSS feed for profiles that can be used to automate tweeting. Content warnings don’t work super great with that but otherwise it’s pretty nice.
