Rate my Sanity update - now with pointless tagging!

It's been a while since I've hacked on Rate My Sanity!!1!, but I've added a small feature now, which was a right PITA to implement.
The site now has Flickr-style tags implemented in AJAX. Totally pointless, but off you go.. tag away! Watch the input boxes fade in and out..

For example, I am tagged as "male" and "geek".
You can browse by tags at http://sanity.dryft.net/tags

Have fun. Does this make it Web 2.0 now? :)
