Danny Sullivan for Search Engine Land runs though some search engine usage numbers, looking at how traffic is going for Bing in these early stages.
It's tough looking at these early numbers because it's very difficult to determine any potential long .term changes when you look a short-term numbers. comScore sees and increase in usage for Bing, but that doesn't seem to be reflected by compete.com's numbers. Danny does a great job of going through the numbers are explaining what's really being measured.
Getting people to change their habits is hard, and I'm still not sure how I feel about Google... What do you think? Is it great or not? No doubt some people will want to use it more than Google just out of principle. Why? Because It's Not Google!
Oh, another Microsoft thing that I thought was funny today was that they are insulting some browsers as part of an Australia promotion called "Ten Grand Is Buried Here". See tarnished Chrome, boring Safari and old Firefox.
