Mark Granovetter, Stanford sociologist, in 1973 in his seminal essay "The Strength of Weak Ties," made the point that these weak ties that are a part of our networks, these strangers, are actually more effective at diffusing information to us than are our strong ties, the people closest to us.
Mark Granovetter,  sociolog sa sveučilišta Stanford, 1973. u svom prvobitnom eseju ''Snaga slabih veza'', ističe da su te slabe veze koje su dio naših mreža, ti stranci, zapravo učinkovitiji u prenošenju informacija, nego što su tu naše jake veze, ljudi koji su nam najbliži.
