Dominance?
Google search is dominant only among those who "don't get it". Even with AdBlock Latitude some of those pesky adverts slip through.
I never thought I'd praise anything from Micro$not .... but, BING is my default search engine.
Of course Google has been trying to dismantle MS for yonks. What with the Chrome "OS" and the Chrome browser, etc. So far as I know Redmond is still hanging in there. Slick Willy Gates still tops Forbes List of the richest people in the world.
Senators - find something to do that actually is productive.
