I came across this article on Mashable.com yesterday and was stunned when I read it. According to TwitStat, UberTwitter is the most popular Twitter client for BlackBerry devices. I hadn't really thought about it before, but if I had I would have surely picked TwitterBerry given its age and ease of use. I guess UberTwitter has won over the BlackBerry nation thus far. UberTwitter accounts for 1.26 percent of Twitter users, edging out TwitterBerry's 0.87 percent. SocialScope, still in private beta, sits at 0.35. Clients like TinyTwitter and TweetGenius also made the list but they just didn't have a great showing. So why UberTwitter? Is it the UI or the ease of use? What has made it bigger and better than the rest of the pack? Weigh in and let us know your thoughts in the comments.
