@nanofthenorth @mikegalsworthy You can use Debirdify - I haven’t tried it, but a lot if people are recommending it. It allows you to download your Twitter followers to CVS and the bulk-upload it to Mastodon.
Mastodon is the best way to keep up with what's happening.
Follow anyone across the fediverse and see it all in chronological order. No algorithms, ads, or clickbait in sight.
