  The Rovelli relational interpretation of quantum mechanics (RQM) is based on
the assumption according to which the notion of observer-independent state of a
physical system is to be rejected. In RQM the primary target of the theory is
the analysis of the whole network of relations that may establish among quantum
subsystems, and the shift to a relational perspective is supposed to address in
a satisfactory way the general problem of the interpretation of quantum
mechanics. Here I argue, mainly through an analysis of the so called third
person problem, that it is far from clear what a relativization of states to
observers exactly achieves and in what sense such an approach really advances
our understanding of the peculiar features of quantum phenomena: therefore, in
this respect, RQM still faces open problems.
