The search engine replaces Bing Live

To my surprise I just found out that Microsoft had just replaced its search engine live (which is very recent) with a new named Bing!
Marcheteau Olivier, CEO of consumer and business Internet Microsoft France presents the new engine Bing in a video interview in Le Figaro. Particular, we learn that Microsoft is currently only 2.8% market share in research in France.
My opinion on the subject: Bing will become a search engine more and more commercial. And one advanced I have seen is the suggestion in the research to refine the results but much less efficient than the engine Yahoo, which made ​​proposals live while writing the query in the search field.
The design is very average (compared to that of live.fr), I wish I could choose a color theme.
And the algorithm of search results ... they change something? :-)
Instead of changing the domain name they would have to focus on what is important to know the relevance of search results.
Nobody needs an engine Web 2.0!
