People can make their own Vine accounts and start to make funny vines, serious vines or just about anything they desire.
People I recommend you follow are: Lele Pons, Curtis Lepore, Christian Delgrosso, Alx James, Brent Rivera, Ben Tremblay and of course you have to follow...............ME!!!! and Josie
When posting a Vine the videos are only 6 seconds long. But they are repetitive. You can loop a video so that is never ending. Well, I can't say that they are always an infinite loop.
Videos are 6 seconds long, like I said before in the posting part. Have fun and watch.
