Vine

When Vine first appeared it looked like a really bizarre social network that could never work. Who records six seconds video clips and posts them online? As it turns out, a lot of people are willing to do this.
The Vine application for Android allows users to quickly capture videos and post them on the online service with as little effort as possible. Of course, the users will also be able to watch what other people are posting, and they can discover and save channels that they like.
Moreover, users ca also post the videos on other social networks such as Twitter, Facebook or Tumblr, for example.
