As I was writing my last post, I searched Google for "Edwards We the People", and was pleased to see my post about the ad campaign on the first page. Thank you, Google. However, the same search in MSFT's Live engine placed my post on the fourth page. Now this may be a simple and ego-centric way of judging relevancy, but I'd venture to say that Google's search results are more relevant to me because it turned up something I wrote!
What more (and this analysis is a bit more quantitative), Google turned up 7.3 million results, and Live only 730,000 results -- a tenth as much!
