Del.icio.us is the greatest thing ever. You should should go to it, try it out and marvel at it's genious. Nowadays I don't have any of my bookmarks on my machine, it's all up on del.icio.us. It's really is something that more people should use.
For example, when I blew away my old hard drive (which I still need to get the RMA for and return) I didn't even think about my bookmarks. It's getting to the point where things are never really living on my machine except for a few easy config files. So when it's time to blow something away, it's not the tear jerking, hair pulling situation it used to be.
