The more I learn about it, the more impressed I am.
I updated my main site to XHTML 1.1 tonight. Didn't have to do much to make it validate.
I'm considering totally reworking my blog layout now that I'm starting to understand how it works. Right now I'm basically using MovableType's default layout with some minor stylesheet changes, but I'd like to come up with something a bit more unique.
I'm considering making something based on my little alien dude theme (you can see it in the background of some of my screenshots). There's just something spiffy about it. =)
