Fictional Fans

Like I remember reading in an anime magazine (bought at a newsstand) about yaoi/boy's love mangas (which I was already aware of at the time since I bought the magazine because of the article) and they listed a few links for websites with fannish content.

So had I joined the fandom when I visited these sites for the first time? I had already developed an interest in queer narratives way before and had consumed anything even remotely related to it (books, movies etc) without calling that fannish. But looking back I would have posted pic spams on tumblr or livejournal about the movies I saw if I had the technical abilities.
