Microsoft, in cooperation with Federated Media and Twitter, launched its own full-blown Twitter search engine today. BingTweets mashes up real-time Twitter search with results from Bing, Microsoft's new and increasingly popular search engine. tweetmeme_url = 'http://www.readwriteweb.com/archives/bingtweets_microsoft_launches_a_twitter_search_eng.php'; tweetmeme_source = 'rww'; The result is an interesting hybrid product that puts Bing's search results at the center of the experience, while the real-time Twitter feed appears in a sidebar on the left.
