ESPN is getting closer! I have written a lot about ESPN's usage - and potential usage - of Twitter. I have criticized and applauded. Here is an example of ESPN continuing to improve. It's a minor example, but ESPN has now allowed in-line actions on their Twitter modules (it used to be just one-way reading, mobile example here). You can now retweet, reply and favorite content inline. Novel idea right?!
It is getting closer: ideally this would be more expansive than a widgety module. It would be more deeply integrated, power group chats, include lists, etc... but, it is getting closer!
