Forget about Twitter being a mere messaging platform. The truth couldnt be more removed from that, what with the endless array of apps that expand on Twitters inherent capabilities. A case in point: the Tvider website. As you can tell from the title of the review, it is a service that will let you tweet out videos along with audio and pictures. The video files that are shared in this way are limited in size (no file can exceed 10 MB), but thats it. You can tweet out pretty much anything except for copyrighted or adult content. But if you want to tweet out a spirited rendition of Rocking In The Free World or a video of your son performing at Thanksgiving you can do that on the spot.
