As someone with 900 plus followers, I wholeheartedly endorse the idea of ignoring "users with more than X followers." For balance, users with less than X followers seems appropriate... but I doubt I'd ever use it. It would, however, be a useful tool for those poor downtrodden masses that see themselves as the butt of the joke here: If I had an account that was a day old, and I felt like seeing what Hubski really looked like, I could ignore users with less than two followers less than a week old and then you wouldn't need that pesky recommendation engine that gave me 900+ followers in the first place.
When a new user joins it simply says, "you are not following anyone yet...."then you wouldn't need that pesky recommendation engine that gave me 900+ followers in the first place.
-fwiw, that pesky recommendation engine has been defunct for a good while now. You are "naturally" receiving these people now.
