I just implemented a kick ass plugin that allows me to tag my articles and create on of those trendy tag clouds.
All joking aside, I have come to like tags much better than categories for organizing my thoughts. Plus I always kind of hated the way the category listing looked— the tag cloud looks much better over there on the home page. The danger becomes generating just too many tags for my own good, but we’ll see how it goes. There may be some style/layout glitches while I fool around with the tags, so please be patient.
