The Windows 8 effect?

In recent days the amount of search engine referrals to jml.is from Bing, as opposed to Google, has skyrocketed. Where, previously, Google took close to 99 percent of the traffic, leaving Yahoo and Bing in the dust, Bing has jumped to 16% with Yahoo all but disappearing. I’d contribute the latter to a new version of IE which got rid of the search toolbars many unsuspecting users get “infected” with, taking any and all incentive or push to use Yahoo with them.
