That statement about this being the first fandom dominated by women is simply not true. Early Trek fandom was so dominated by women that mainline SF fen were at a loss as to why their formerly 85% male conventions were being flooded by women, and that was the case well into the late 70s/early 80s (my first Trek con was in 1979, and over half the attendees were female). Trek fandom didn't become the province of male geeks until after the first or second movie.
