Oh yeah, I started using Vine App. It’s kinda neat to toy around with and make 6 second videos, though I’m not really sure how much I’ll end up using it.
There is an interesting website where you can check out instant, real-time uploads from Vine users all over the place. They are public, after all. It is disturbingly voyeuristic, but at the same time it provides a fascinating glimpse into society, from goofing off during class to playing with kittens. Check it out.
