I found an interesting thread over at the old Cre8aSiteForum named the -noblog option or blog tab: can it be done?. This post brings up the question as to whether Google will had a filter option to exclude blog pages from the results.
Most of you reading this blog already know that Google happens to treat blog-like Web sites very well, often ranking blogs very well in the SERP. People who have ordinary content sites are upset by this, whereas those with blogs are thrilled. So rumors are spreading that Google might be adding a filter.
This thread discusses people's thoughts on the rumor, brings some history (including the Google Bombing) and more. Add your thoughts to this thread at http://www.cre8asiteforums.com/viewtopic.php?t=6294.
