Joi Ito comments on the potential for Google to filter weblogs from search results, and makes a great point.  Isn't the filtering of weblogs just a work around for an inflexible and/or poorly conceived page ranking algorithm?  If the page ranking algorithm returns weblogs in the top tier of results for a search, shouldn't Google consider modifying its algorithm?  And if so, how exactly should it be modified?

Personally, I don't think that Google should change anything about how it provides results for searches.  But if they do insist on removing weblogs due to their prevalence in the top rankings for many searches, how about improving their algorithm which determines page rankings instead of removing the results altogether?
