I also tend to do a twice-yearly cleanup, though this is getting more ruthless as I get rid of things I no longer want or need and can't justify hanging on to. I don't know what's going to happen to all this stuff once it's out of my hands, which is the only part that bothers me. I don't want to just top off landfills with useless crap - but that's also going to influence my spending (or non-spending) now.
