There is much talk nowadays about the “wise crowds” that automagically emerge on social media to democratically decide what is news or what is knowledge. Some believe that the Internet creates a liberating “crowd edited” source of information. Some take the idea with a pinch of salt.

For example, of your 000s of friends, only the posts of some keep coming back to your wall. What decides the order in which these posts are ranked? It is the weight of each friend in your network, which Facebook calculates on the basis of the strength of your interaction with the said person. The formula looks something like this:
