request for bloglines recommendations

so, i set up a bloglines account so i can peruse amusing and cool sites without having to remember pesky things like "man, what was that cool site about that thing with the other thing?"

i've got librarian.net, some political wonking sites, sharktank, kuro5hin, the map room, memepool, gizmodo, bill gibson's blog, and engadget, among others. what else should i be watching, and why?
