I just downloaded IE9 and was testing it out. A very good and very fast browser. IE9 is pretty much a home run from Microsoft IMO. Looks really nice too.
The problem I'm having is, that when you type in the address bar and choose to search for something, like for example, webmaster world, it will instantly bring you to this site. It wont show serps or anything. Which sucks big time for all those other webmaster world sites if there are any other sites.
I think with IE9, a lot of people who aren't authoritative sites, are gonna go way way way down. Like type in "Finance" and it goes straight to finance.google.com =/ That's not cool at all.
Also I did not look through IE9 to see if this can be changed. Seems to be only doing it with Google and not Bing in IE9 beta.
