There's many, many items in our modern lives that don't belong in a landfill, but I don't know what to do with them. So it's either throw them out or hang onto them, and stockpile random, useless crap.
Or, I can try and find out alternative methods of disposal.
Previously, I had mentioned what to do with worn-out clothes. Just this week, I also happened across an article on Wired.com called "Reduce, Reuse, Recycle Your Old Gadgets." From computers to air conditioners to TVs and monitors, they give suggestions on how to get rid of everything. If you're married to a computer guy (and/or you are a techie yourself), this is very helpful advice!
