There was a fair amount of stuff in there that I "knew" I wanted to read (some LW sequences stuff among them). I've found a bit more success by putting things I actually want to read in my top-level bookmarks, right at the front, because then it causes clutter which I want to reduce (by reading and removing them). The difference may just be in that I'm less likely to bookmark something with this system in the first place, but it feels like it works.
