Not IRL, but texting, via whatsapp, photos via snapchat and instagram.

In real life social networks are ephemeral. Someone you meet at a party and have a good time with for the duration of that party is immediately part of your near intimate social network, at least now. You might even share personal things with that person. The next day you might find it weird if they called you however if you didn't leave the night explicitly on some kind of terms to hang out more.

Over time we grow closer to some people and further away from others.

Facebook isn't engineered to do handle this. It just wants more and more data, more connections. It doesn't reflect real life. Build a social network where friending and un-friending is determined algorithmically, based on the number interactions and type and their content instead of a button you have to toggle and it may be take off. Problem is, you'd have to own all the channels through which people communicate.

Turns out people don't want to have to maintain a social graph.

The original social network: speaking to people IRL.

I'm sensing that many people now avoid anything that resembles a 'social network', as if they tried it and are now over the whole concept. Facebook left a bad taste in a lot of mouths.

Edit: NPR's All Things Considered did a story on this exact thing a while ago: http://www.npr.org/blogs/monkeysee/2013/06/17/192718821/teen... and apparently Twitter, Tumblr, Instagram and Vine are big ones for the teens they talked to.

"When people leave Facebook, where do they go?"

Out?

Yes, it is called the Internet.

Snap chat. Sexting is the new communication.
