Mastodon
The Mastodon bridge tool has got a facelift! https://bridge.joinmastodon.org/
You can sign in with Twitter and Mastodon to find Twitter friends in the fediverse. You can also send it to your Twitter friends, as it will show them their friends on Mastodon and point them to where they could make an account!
