Automagic SEO, limitless customization, caching control, excellent community support. I may be biased because I'm a programmer but WP is tickling all the right spots. - Daniel J. Pritchett

Great list of reasons Daniel. When I first started blogging, I just picked Wordpress because I'd read about it somewhere and wanted free/hosted. Turns out, there's so much more to Wordpress. - Hutch Carpenter

Thanks Hutch! I knew from the beginning that I'd want to move to WP if I ever started taking my blog seriously. Back in July I wasn't sure I'd stick with it for very long so I just chose Blogger because I knew I could get it started with minimal effort and no money. - Daniel J. Pritchett
