Introducing Vine (vine.co)

I've already got the app. It's awesome guys. I will say though I hope the app store search allows you just to search 'vine' because I had to search 'vine made' to get the app to show.

Please tell me what this does on your website. Some kind of demo would be nice, too :D

http://vine.co/blog says "Today we're launching Vine... Vine has been acquired by Twitter." So that was fast.
