It's one of the fastest growing apps out there, building its popularity on the idea of self-destructing "snaps." You can send a photo or short video as a message (a snap) to a friend, which automatically disappears a few seconds after they've viewed it.
Kids love this app because it takes the pressure off of having to share something with everyone like they would on traditional social networks.
Users can customize their blog theme, create blog posts in all sorts of different types of content formats, follow other users to see content in their dashboard feed and be followed back.
Reblogging and liking posts is a popular way to interact.
Despite being owned by Google, You Tube can still be recognized as a separate social network all on its own as the premiere place online to go to watch videos on every topic under the sun and upload your own as well.
