Quotations
I can't speak for Faye as ed of FHAPA, but it would be really swell of someone could send us a set of Intersection daily newszines, plus any con flyers or other fannish papers that were there to had for the picking up: fannish things, you know, not including media, gaming, filking or costuming, fine fun but not my cup of blog, thank you.

Arguably, though, “Jericho” fans are just television fans at their most fannish, meaning (still, and after all these years) most Trekkie-like. Fans of “Star Trek” continue to represent the gold standard for American fandom, not only because they were the first to love a television show to distraction (and communicated that love before the Internet), but also because they spun from that love the breath of life.

At any point in our fandom journey ― whether in our first fandom or as a fannish veteran, whether in the very first stages of falling in love with a text or slowly removing ourselves from a community, whether leaving a fandom bitterly or transitioning to a different mode of engagement ― we tend to feel strongly about the fan objects, their creators, and our fellow fans.
