"The question now is whether or not you think social search really is the all-important future and holy grail of accurate search results. If it is, then Bing could have a leg up on Google in the form of around 600 million avidly "liking" and constantly connecting users - something Google isn't likely to see any time soon. After all, Microsoft just isn't angering the masses like it used to. It doesn't seem like that much of a stretch for Microsoft to bring in Twitter data. And besides, remember, Twitter is NOT a social network. Which network would you want in your attempts to provide social search - the not very social Twitter or Facebook, the site with its "like" button on more than 2.5 million websites worldwide? We'd put our money on Facebook." - LANjackal
