Twitter (News - Alert) has been hard at work hyping a big “mystery” update to its service, and they finally unveiled what that update entailed on the Today show, Tuesday morning. 

The update Twitter had been building was a change to profiles, which should now include larger profile pictures for the Web application, and a revamped iPad application. Twitter CEO Dick Costolo (News - Alert) unveiled the new features of the revamped Twitter applications and it appears that most on the Internet are a little disappointed that the buildup has led to bigger pictures.

Social networking sites like Twitter and Facebook (News - Alert) are always looking for the next big way to get a leg up on the competition, and Twitter can certainly do that with the right adjustments. 

Costolo unveiled these new profile pictures by first changing over the profiles of the Today show hosts, saying people will get to know each other better if they are able to better see the kind of photos they put up.

Part of the problem is that there isn’t a whole lot Twitter wants to change about the way it operates. The social networking service has been able to work with other sites like Facebook, rather than compete directly with them, because they offer a different kind of interface. 

Twitter doesn’t do itself any favors when it gets the Internet all fired up for big changes when there aren’t any big changes to be had, but the site would actually be better served to make small changes that are manageable, while still keeping the way the site operates basically the same as it is now.
