Vine is an app that allows you to record, edit and upload 6 second video clips and then share them across the web with just a touch of a finger. Also, Twitter owns it.
Well, I wasn't blown away either which is why I haven't used it yet. However, there's a new website called Vinepeek that scrolls through uploaded "vines" in realtime. If you're still not convinced that this is cool, I dare you to go to the site and not get stuck watching random 6 second clips that strangers have filmed.

I can't wait to see the clever ways people will use Vine like for porn and nasty comments. But hose two things already make up 99% of all the content currently on the web so no big deal.
