Let me explain why I don't use Yahoo and Bing to search for "Yahoo".
I am a "Yahoo" investor and I want to know all the latest important news of Yahoo everyday.
If I make Yahoo my favourite website, I still could't find the latest news about Yahoo, right? Isn't that funny?
What MSFT and Yahoo has not realized is that:
More and more internet users are using Google to search for news instead of just some websites or piece of contents, they need to be able to target latest news about specific objects that they are interested about.
I don't know why MSFT couldn't make it work in Bing, maybe either the engineers or the management of MSFT are not smart enough to do it?
