My Del.icio.us tag list. If you're not a del.icio.us user, think about starting. It's a great way to quickly 'tag' things of interest so you can find them later. I use it half a dozen times a day to mark things I don't want to lose track of, and, it ranks them for me over time showing me what my thought process flow is in a semi-graphic highly alpha mannor. Cool stuff.
