I wrote a bot that provides randomized follow suggestions (from its follower list) -- https://botsin.space/@FollowFriday
As for interesting people to follow (biased in favor of people who post interesting technical content) I recommend https://mastodon.social/@natecull, https://cybre.space/@a_breakin_glass, https://mastodon.social/@hisham_hm, https://mastodon.social/@tomharris, and https://hackers.town/@thegibson
I'm at https://a.weirder.earth/@enkiv2 at the moment.
