Summary: Microsoft wants to expand their search market. They plan on spending a lot of money advertising this. This is a bad idea.
Guy who wrote this, listen up:
People do not giving a flying shit about the underlying architechture of any product they use. They do not care about the quality of results. They do not care about the logo on the top.
They care about how they feel when they're using things.
Lets look at apple's ipod. Yes, they are absolutely successful. Why is this? Is it because they have a massively superior product to anybody else? Or is it because they have advertised the living hell out of it to the point of an ipod being a fashion accessory/status symbol?
Haha, ipods are so hip, what, are you behind the times with that other mp3 player? Haha, look at how happy I am with this terrific, iPod, I'm with it! I'm hip!
The ipod isn't better, the feeling is better.
Look at the bing homepage compared to google. They have a nice big graphic on there with lots of colors. Its kindof beautiful. Oh, and the graphic changes all the time! Isn't that great? It's like you'd have to go to the page a few times a day to see all the pictures.
(now I'm adopting that annoying, sarcastic writing style. Sorry)
In search, getting results is the easy part. The part that keeps people coming back isn't content, its the feeling that they get when they're using the product.
