You’ll remember, once upon a time, tweets were top dog in Google search. And then that relationship dissolved in a sea of vagueness and although you’ll see tweets come up in Google searches today, they’re noticeably appearing after the more Google-y bits of information (like news stories and such, capable of being +1′d on Google+). This is, of course, just as the Twitter Oracle predicted.

But enough about Google, we’re talking Yahoo here. And Yahoo is busy cozying up with Twitter, much to (we imagine) someone at Google’s chagrin who must be thinking, “Maybe Yahoo isn’t as irrelevant as we thought!”

Marissa Mayer means business. As Yahoo’s head honcho, she has proven this time and again. And now this former Google executive appears to have set her sights on smacking Google back and locking up “real-time search” for her new employer:

Updates direct from politicians, celebrities, media outlets, and other publishers have become an important source of real-time news and information. 140 characters can connect athletes with their fans, capture live chatter from the red carpet, and inspire global debate.

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.

Yes, just as Google used to. Interesting.

Mayers also mentions that the results will be personalized. All Things D points out that “’personalization’ has been Yahoo’s huge pitch to court users into making Yahoo their destination site for the Web, including signing them up for Yahoo profiles. The more Yahoo can tout a personalized experience tailored to what the user wants, the better that pitch becomes over time.”

It’s not clear right now if having a signed-in Yahoo profile connected to your Twitter account will affect what tweets will appear in that news feed, but I’d imagine if Mayer wants to claim true personalization, that would be a good way to do it.

It’s also not clear if Yahoo News editors are curating the tweets themselves, or if they’ll have their news algorithms do the work.

What IS clear is this: Yahoo’s coming for you Barbara . . . erm, Google. Mayer and Yahoo are coming!
