Another Twitter Ad: AT&T Sponsors “March Tweetness”

Earlier this week, Twitter started rolling out its first ad experiment–an “ExecTweet” page, sponsored by Microsoft (MSFT). Here’s the next one–a “March Tweetness” page, sponsored by AT&T (T).

Everything about the newest ad gambit is parallel to the earlier one: It’s run via Web ad agency/network Federated Media, and consists of a page that Twitter endorses and will promote on its site.

And just like the ExecTweet page, most Twitter users won’t see Twitter’s promotions since most Twitter usage happens away from Twitter.com. And just like ExecTweets, March Tweetness is a collection of themed Tweets that you could find on your own, using Twitter’s handy search function, which it paid $15 million for last year.

But this one looks marginally more useful to me: Unlike ExecTweets, there is a rhyme and reason to collecting Tweets tied to specific events–in this case, different games during college basketball’s March Madness tournament. One of Twitter’s most compelling features, after all, is its ability to deliver snippets of thoughts, in real time, so I could see people actually using this one.
