I just wanted to point out that I just made my blog mildly more 2008-compliant by activating tags. I haven't put them in for all the entries yet, but somewhat recent ones, yes. You'll find them at the end of each entry.
Don't ask why I waited until now to actually make them appear (I had been inputting them into entries for a while); fiddling with Movable Type's template tends to make me want to throw objects and strangle things, so I avoid it as much as possible. While making the tags work, I also fiddled with the search page template, which looked like a bucket of crap for the past four years.
SO SEARCH AWAY! And click on those tags. And if the search page or tags looks weird in anything besides Firefox, well...it's still functional.
