Tags
I have gotten quite into tagging. Here's my philosophy on this.Some definitions of my public tags. (Notice, how it contains a subdivision into tags that are applicable to bookmarks, blogs, images, etc using yet more tags.)
It also contains pointers to tops of link clusters (overviews and centers)
Some old public tags.
For fun, I've tried to make my delicious tags available in a variety of formats.
