Recommendations, which we also sometimes call "word-of-mouth", are as old as the world, they're free, and they can pay off! The alternative would be to "advertise" his activity. But there, you have to be ready to lose an arm! When you are looking for a doctor, a lawyer or a butcher, and even if you are looking for all three at the same time, you generally start by asking those around you for advice, in the course of a conversation: "...hey, you wouldn't know a good doctor-butcher specializing in business law.
The opinions of our acquaintances are obviously much more valuable than any search result on the internet. Therefore, it is with a relatively high level of confidence that we will hasten to request an appointment in this cabinet "Medico-butchery and associates"... even if background remove service it means waiting a few months! We are then in a position of desire...ready to accept a higher price or a longer deadline... For the design it is the same thing. Why entrust your communication to a stranger when you can entrust it to an acquaintance! Friends of my friends are my friends! Today, the level of trust is still high in real life, but we can imagine that in the future, social networks will arrive at the same level of trust as in real life.
By the way, don't talk Do we not have "TrustRank" (google) and "Like" (Facebook): the recommendation is certainly a value for the future!

I then forget to remind them of the theory of the 6 handshakes , a theory established in 1929 by the Hungarian Frigyes Karinthy. It deals with the possibility that any person on the surface of the Earth can be linked to any other, through a chain of individual relationships comprising a maximum of five other links. Basically, everyone is an acquaintance of acquaintance of acquaintance of acquaintance of Obama. From this observation, we all have a network.
