Using categories for blog posts is a nightmare: You start off with a generic category name, then you're tempted to split it into multiple categories, at which point you realise said category contains 428 posts begging to be reorganised. So you promptly give up on reorganising the categories and go play Wii, or eat a cookie, or something. So I've adopted a new little plugin for WordPress called SimpleTags. It makes it easy to add Technorati tags to the bottom of a post, and can also be used to create a tag cloud. Sure, tag clouds are oh-so-2006, but they're also an interesting way to see what I've been blabbing about recently.
We'll see about the tag cloud later, since I've got a stinking head cold, which makes it hard to even keep my eyes open, but the plugin was drag and drop, so that's in use already.
