What you are describing is basically Instagram. No "sharing" or "reposting" other content, only original posts from friends. Some have found ways around that but it's not the default.

I'm not familiar with Snapchat but I expect they have a similar mechanic. It seems like the newer social networks are avoiding the problems caused by virality, and getting back to the original reason we wanted to join social networks: to see what our friends are up to.

Interesting, a bunch of my instagram friends use it to share memes and reposts. Facebook seems to have more "personal" photos whereas instagram seems to be (at least amongst my friends) more of where they share cute random images or pictures of celebs, what bands they like, etc.
