Think Twitter's going to follow Facebook and lend its brand to a smartphone? Think again. Twitter CEO Dick Costello said during his Mobile World Congress keynote yesterday that while he does see a need to better integrate Twitter into existing platforms for phones, he sees no need for a Twitter-branded smartphone. Costello cited the ability to take a picture on an Android phone and automatically tweet it as an example of that integration he'd like to see, and further added that he would like to see "more single sign-on experiences," and "more apps that can tweet without having to go to another app." Interestingly, Costello also revealed that 40 percent of all tweets come from mobile devices, and that fully half of all active Twitter users are active on more than one platform.
