I'm another one of those that switched from MT to WP in the recent ruckus. It wasn't because of the licensing fiasco, but because it wasn't such a big update over the previous version, and I got tired of waiting for 2 minutes for a mere 200 posts to rebuild. I've always enjoyed the dynamic nature of PHP more.
I've converted my site, Good Blimey!, to use the new 1.2 beta version, and am loving it. I was amazed at how easy it was to import the existing entries and get everything back to where I like it. I've also redesigned my blog, and while some people won't like the color scheme I chose, it fits with the theme I created.
Feedback and suggestions are always welcome.
