Competing with Google for search traffic is no easy task, even for a software giant like Microsoft. Unique features and customization have helped keep Bing afloat, though -- and now, MS is counting on some more comprehensive Facebook integration to boost appeal. Beginning today, the site's "Social Results" sidebar will be pulling in a bit more Facebook content, including posts from your friends that the tool deems relevant to the search at hand. You can also pub directly to your timeline from within the tool, sharing search results with your online buds. It's hardly a revolutionary refresh, but if you haven't yet managed to annoy your friends with posts about your favorite Spotify tracks or those shoes you just purchased online, Bing's now ready to step in by making your search habits public, too.
