I wonder how well blogs would work to publicize websites. Especially since google now owns blogger.com The blogs are indexed locally by google and don't need to be crawled. I imagine those blogs get indexed very quickly. That, and blogs are often updated and high traffic.
I've created a blog to test this theory. Anyone can post to the blog through email. Please don't spam or abuse this, as I'm sure that would be a violation of the use policy set out by google.
