I was wondering how the "X post" or "4 stars" info was making it into the google search results. I was thinking that google may have been parsing the data somehow, or that the site itself was providing that information somewhere. It seems that if google is indexing microformat information, it has some foot hold already. If the microformats specs are as bad as Atwood makes them sound, hopefully the attention they are receiving will force them to tight the spec up.
