@SEO101..  I didn't post here for a evaluation...  Read the threads message again - listen to users feedback..  I'm not real sure why you care so much about this thread or search overall if you say a "based on a free ride from any search engine is NOT sustainable in the long term"..  Must be just a hobby for you??  

Did you read here: http://www.mattcutts.com/blog/algorithm-change-launched/

I'm not a newbie and have seen a few algo changes in my time..  I've been through my ups and downs and am usually fairly confident an issue a site might be having.  

I do say thanks for the seo101 threads you posted..
