I'm constantly surprised at the number of people who are looking for lists of people to follow. There's no shortage of fascinating breadcrumb trails here.
Pick a toot that resonates with you and open it up. See who commented, or retooted it. Look at those people's profiles. Follow them.
Look at their older toots and follow the people whose comments on those toots pique your interest.
I've been here a month & have a global circle, not one of whom I knew before coming here. #IFollowTheCrumbs
