I'm on WordPress Now

If you find yourself on this blog then you need to click on http://www.postednote.com to get to my actual blog which is now on WordPress. I like WordPress, but what about TextPattern? Have you used it? What do you think? What are the benefits of switching to a more robust publishing platform? For me it means less spam and more control over archiving and tags, but are there other benefits out there that I don't know about?
