In addition to providing links to Twitter messages, Bing will extract the URLs of the pages that the messages are making reference to, so that users can go directly to that source of the information.

When providing links to "tweets" that contain a shortened URL, Bing will put in parenthesis the main Web domain of the link, so that users know, before clicking, whether it's a reputable site and thus avoid landing in a malicious phishing or malware-laden site.

Bing will also display a tag cloud of the most popular Twitter topics, so that users can click on and dive deeper into them.

The Twitter deal is nonexclusive, and hours later rival Google its own agreement with Twitter.
