Twitter is testing a major profile redesign that's very reminiscent of Facebook and Google+.

I agree with Bill here. I also liked the Tweetdeck for when I was posting media. We've seen Facebook move to a similar Google+ adjustment, and it makes sense that most social media sites would do the same.
