The incapacity within the current social media of fragmenting our identity
Social networks does not allow to fragment these multiple identities. In other words, we can only have one profile on Facebook, where we express all our points of view and experiences, whether on the crisis in the Middle East or about the paella we’ve cooked this afternoon. This situation is what leads us to hit the “unfollow” button, when we really just want to stop following one of their identities (which we do not like or bores us).
Will Facebook implement a system of multiple identities someday? The answer is very clear: there’s no way. The Facebook business model is based on having the most information about a single identity (their tastes, their experiences, their plans), to monetize this data. There can be no interest on the part of the network to divide the person in several profiles because that would make more complex the task of collecting and cross the user data.
Summarizing, some of the limitations of social networks are insurmountable because its business model. We can still dream of a social network that is really built according to the real user needs, but it won’t be any of the existing.
