I don't think I have a need to remove anyone from anywhere really.

Nobody is posting obnoxiously much on LJ. My MSN lists are divided in two, people I talk to and people I don't talk to. Sure, I probably could've deleted one of the lists, but it doesn't bother me at all to keep it minimized. There are some facebook friends who needs to tell me every little goddamned thing they do, but I have those placed in a "no news feed from me" group, so it's basically like they don't exist, except from the times when I want them to exist. It's all quite convenient, really!
