Everybody's gonna find their own way on here, but in case helpful to any other relative newcomers...

I had avoided using tools like Movetodon that let you easily follow all your Twitter follows, bc I wanted to start fresh.

But I was finding it a bit quiet, so today I used Movetodon and sorted the list to show the most recently active users at the top. I selectively followed about 100 of those, and now my Mastodon feed is much livelier. https://www.movetodon.org/
