It occurs to me that although Google have a huge market share, MS really is going for it with this one. Live messenger now sets your home page to Bing, if you allow it and loads of people will do, and they have the huge Hotmail network to promote to.

So they have many routes to market that Google don't necessarily have. It's an exciting time as, although I have been an avid Google user for the last 8 years, I do like the idea of a new runner in the search engine race.
