This is my presentation about social media.

1.  I use Facebook a lot if I have a few minutes of free time. With
Facebook, you can post statuses, videos and pictures as well as
like and or comment on them.

2.  I like to use Vine now and then just to watch funny videos. On
vine, you can only post videos with lengths of up to 7 seconds.
You can also like, share, and comment on these videos.

3.  YouTube is a great place to listen to music, look up reviews for
products, learn new things, and watch all sorts of other kinds of
videos. Only videos can be posted to YouTube, but they can be
any length. You can like, share, and comment here as well.
