More Meta-Memage, or The Perils of an Overstuffed Friends List

I fill out a fair number of Memegen memelets just for my own amusement, though I don't post them because I doubt anyone else really cares. But the problem is, half the people on my flist are people I don't actually know, or joke journals and other things of that nature, and those show up all too often in the slots where I'm supposed to see the names of my friends in silly contexts. This seriously cuts down on the amusement factor. Wish there were something to be done about it.
