An "active followers" count would be more informative. Like, only people who have been active within the past 3 months, or something.

Number of lurkers doesn't really say much, as anyone can view our notes without loggin in, over the Internet. And, if I could have an active-follower list, I'd be inclined to peruse it, to see if anyone interesting is in there. They're following me, right? So, they might be pretty cool, right? 🤔
