No large medium that I am aware of ever succeeded without major commercial backing and content. So is google sticking to its roots and slamming the commercial world of the internet? I think that in months to come Google will be changing again when searches drop. I am hearing all over that they are starting to look at other search engines again as they dont have the time to weed thru the garbage at the top. Searchers want to compare relevant sites. Not get one or two out of ten. I am sure Google will be watching search numbers carefully.
