Around the beginning of May, reports came out suggesting that Twitter had acquired TweetDeck, and an announcement was expected within days. That didn’t happen.

Here it is several weeks later, and now we have a report from CNN indicating that the deal is done for over $40 million in cash and stock, citing “sources close to the deal”. The papers were signed Monday, according to the report.

Twitter is evidently still holding its cards close to its chest, and considering the whole thing a rumor, as far as the public is concerned.

Perhaps they’re just not ready to answer all of the questions that will come with the acquisition about the future of TweetDeck and the future of Twitter’s own platform.

UberMedia had intended to acquire TweetDeck earlier this year, but that never happened.

Shortly after Twitter co-founder Jack Dorsey returned to Twitter a few months ago, he was quoted as saying, in a talk at Columbia University, “TweetDeck is a very interesting client, because it presents a view that no other client in the world presents, which is this multicolumn, massive amounts of information in one pane. And people really, really enjoy that. But I think that’s maybe five percent of the Twitter population. That five percent of the Twitter population are some of the most high-value publishers that we have, and they’re using the service at extreme velocity. So of course we have to pay attention to that, and I’m not saying we need to rid ourselves of interfaces like that. We have to embrace them.”

Consider TweetDeck embraced.

That 5% should grow significantly if Twitter rolls TweetDeck features into its own interface.
