Twitter just launched Vine, a new standalone app for the iPhone and iPod Touch that also integrates into your Twitter timeline. It's the latest in a long line of "the next Instagram" attempts--not too different from Cinemagram, an app which had a mild and short-lived vogue last year and allowed you to make short GIFs.

But instead of a GIF, a "Vine" is a short, 6-second-maximum looping video, which, unlike Snapchat or Poke creations, does not self-delete after a few seconds.
