We will talk a lot about social media, social networks and all around it, because these subjects are intrinsically related.

The play factor is something that you do for an audience, to make them (your readers, spectators) engage with your content. To make them talk with and about you. So, the dunbar number is a very important component. You should see it as a limit, a concept and a challenge.

The idea is that a human being in uncapable of having networks of friends beyond 150. Oh, well, you can have more friends than that, of course, but we are talking about having a real relationship with this network. (To tell you the truth I doubt that I am capable to even relate to half of this number. But I digress.) Even then, he/she, on average, will answer messages from, let’s say, 7 to 10 of them. This is seen as cognitive limit and should not be overlooked.

There is an interesting article on The Economist about the subject.
