Since this is Bing's first spring (the decision engine was launched on June 1st), Microsoft has thought about making it as special as possible and what else can ensure that if not some functionality updates
There's no official news yet to link to, but since I use Bing all the time as my default search provider, I found out just, like, a minut ago that Bing is finally gone HTML5 :D . Go check it out at www.bing.com of course :D it looks awesome and I'm trying out the new tweaks right now :D
