The outlook looks good for Bing too. Microsoft announced a renewed Bing search deal with Twitter on Tuesday. The deal will see Twitter continue to share its tweets with Bing search results.. Bing uses Twitter data for its real time search queries, something that Google had to temporarily disable after failing to establish a new agreement with Twitter. Microsoft is also preparing to unveil a new Bing web app for Windows 8. The web app will include a tile based version of Bing with touch friendly navigation. The software maker is expected to make the web app available with copies of the Windows 8 Developer Preview.
