Here's what friend zoom is all about. See the screenshot. So you've got a 0-99 slider like this for every connection. Then this slider is at the top of your stream. If you move it to the left of wherever you set a particular connection (contact/follower/whatever) , the screen updates and they aren't there. The idea is you want close friends towards the left and random followers towards the right. Then zoom in and out on demand. New connections always start at 80 so if you do nothing they're still above the internet riffraff at 99.
