I'm not talking about confusion as to the definition of RPF bust just that RPF is now more closely defined as fan fiction, where as in the past it was the bastard child to be stomped out, not defined as fan fiction or not seen as a legimate part of that community. Aspects of crossing over even different characters played by the same actors was considered some what taboo in places. As RPF becomes more accepted and part of the community for all of fan fiction, those other barriers between actor and show probably begin to break down and people just define them the same way...
