So today, in fits and starts throughout the day, I went through all my browser bookmarks and tagged the ones that still worked, and now I have them all nice and organized. The whole process went so fast -- almost two hundred links, and I classified them in a matter of hours. Almost ridiculously easy. It had gotten to the point that I was reluctant to add bookmarks because I was afraid I'd never find them again. No more. And of course having them classified and cross-referenced appeals to the librarian within.
It's a great tool. Definitely recommended. Now I'm tempted to go through all my LJ entries and tag them in del.icio.us. But that's another project for another day.
