Yahoo! last night announced that it has struck a deal with Twitter that will bring the microblogging site to Yahoo! and its many Web properties, letting Yahoo users access the stream without actually going to Twitter.

Users will be able access their Twitter feeds from the Yahoo! homepage, Yahoo! Mail, Yahoo! Sports, and other various properties, meaning that users won't actually have to surf over to the microblogging site to check up on their followed. In addition, from those same Yahoo! properties, users will be able to tweet out to their followers. Finally, updates from the entire Twitter stream will, effective immediately, start showing up in Yahoo! search results.

Bing and Google struck similar deals just a few months ago, bringing Twitter content in the form of mini-feeds to their search results. If it wasn't obvious already, the search giants clearly see great value in the vast store of real-time updates coming through Twitter every single day.

"The information in one single tweet can travel light years farther with this Yahoo integration," said Twitter co-founder Biz Stone in a statement. "Tweets in more places brings relevance where and when you need it most."

A couple days ago, Twitter revealed that it is now seeing about 50 million tweets per day. That's some serious data, especially considering that just a year ago, the small microblogging startup had only been seeing about 2.5 million tweets per day.

According to Yahoo, the real-time search integration should already be live, while the extra features will be launching later in the year.
