This paper discusses ways of navigating online contact networks - networks of social connections defined under a relational context - on a way that can provide much more meaningful information to those that use them. In particular we use the concept of a weak and strong relational tie to address the different levels of social distance and express them using a trapezoid function of fuzzy numbers. We provide a numerical example using a fuzzy graph where the strength or weakness of the connections is defined as a fuzzy number and address some of the advantages of this approach to provide better information for the members of this contact network.
