I third that!

I created a blog about my industry a month ago, for free, and I am already showing 1st and 2nd page rankings on MSN and Yahoo for my keywords, right next to the "big guys". Search engines love blogs, will crawl fast and rank them well. I am working on a 2nd one and hopefully will soon create a network of blogs.

I am currently experimenting a special XML-RPC request for Yahoo's API that notify yahoo of a new post. If yahoo receives this request, it will come crawl your new post very fast. How cool is that!

I think blogs are the way to SEO right now.
