Love me, love my word cloud. These are an interesting reflection of what's going on at any given point in time; if I took a word cloud snapshot of my site once a month for a year, I wonder what that would look like. Would I find out the secrets I keep even from myself, or would I learn, finally, that I've settled into some pretty serious ruts?
(Added later: Hey, if you use del.icio.us (and you should, man), Oliver Steele has a cool app that gives you a window on your tags over time here. Bonus points for naming it Expialidocio.us)
