Attention Yahoo users: you’re about to see a big change to the homepage newsfeed – tweets.

Yahoo CEO Marissa Mayer announced the new partnership today in a post on the Yahoo blog. “Tweets have become an important information source for many of our users, so we are thrilled to announce our partnership with Twitter to bring Tweets directly into the Yahoo! newsfeed,” saus Mayer.

Look above. Notice anything different about the Yahoo newsfeed? I know, it looks the same – but look closer. Direct your attention to the third item on the main feed. Yes, there it is – at tweet from ABC World News, complete with a timestamp, link, and a follow button.

“As users explore our nearly endless stream of content, we will seamlessly include relevant and personalized Tweets alongside stories from Yahoo! and our other sources. With this greater breadth of compelling content, we’re excited to give our users even more opportunities to learn and connect. Users now also have an easy way to discover relevant and interesting people and publishers to follow on Twitter, personalized to their interests and preferences,” says Mayer.

Relevant and personalized – so that seems to indicate that users that are signed-in to Twitter will enjoy a more robust experience with the new integration. The types of tweets that will fill Yahoo’s newsfeed will come from all types of newsworthy areas including sports, entertainment, music, and more.

Mayer says that the Twitter integration will rollout to U.S. desktop and mobile users in the next few days. No mention on the terms of the deal, however.

Speaking of partnerships between Twitter and search companies (I know, but Yahoo is still primarily a search company), Google and Twitter had a famous falling out back in the summer of 2011. Thanks to an inability to reach an agreement Google’s realtime search, which leveraged tweets, got the ax. Google talked about it’s imminent return shortly after the failed deal, but nearly two years later Twitter and Google are still on the outs.
