12seconds.tv (currently by invite-only) is a new microblogging platform that allows users to record and share short video snippets of their life – what they are doing, where they are, and what's on their minds. Anyone with a webcam or mobile video recording capability can use the free service.
Just like Twitter's 140 character limit, 12seconds has a limit of, well you guessed it, 12 seconds. The idea is to share brief moments of your life, instantaneously, spontaneously, and on the go. Users also have the option of linking their 12seconds accounts to their Twitter accounts.
