Why twitvid.com is going to تكسّر الدنيا

I was pleasantly surprised to see that twitvid.com changes your page background as soon as you log in with your twitter info. That adds to the numerous other functionalities they're offering, such as uploading multiple videos at once, real-time uploading, and using your webcam to upload a video directly without saving it to your computer. Also, with their Mobile video uploading, and the almost certain 3rd Gen iPhone video capabilities, I am expecting this service to be huge.
