Her prompt: Has Fandom changed since you joined it? Do you have the same feelings about Fandom now as then?
Wow, all right, I think the real answer to this -- after meditating on it for a day and a half -- is: my fandom experience has shifted so much that I can't possibly compare then and now in a relevant way.( Three Points on my Fannish Timeline, For Reference )
To me, my fandom experience(s) have been so disparate from fandom to fandom that I don't really think of them as a progression, where change might be observed and attributed to Fandom rather than to quirks of a particular fandom. For one, I seem to zigzag across the book/film and anime/Western animation lines quite a lot, making it very hard to tell cultural differences from progressive changes; Gundam Wing and TPM weren't all that far apart in my personal timeline, but the "culture" of each fandom was quite different, which I attribute more to the community (and perhaps the greater connexion and the medium than to evolution of fandom itself.
I feel pretty lucky about the breadth of my fandom experience! I have been to a SF/F con, an anime con, and HP midnight book releases (in costume); I have met fandom friends ranging from teenagers to grandmothers; I have a basic comprehension of a number of fannish cultures, from the mainstream (HP, Star Wars) to the obscure (Lois Bujold, Eroica) to the obscure-within-the-mainstream (HP/SS in Harry Potter). I know how to read a manga page and where to find fic for a tiny novel-based fandom. I can compare slash and yaoi, have friends in both camps, and enjoy both styles, as well as where they overlap.
Now, post-HP, I'm in that odd limbo of "looking for a fandom," which is interesting and aggravating. (I got entangled in Loveless for a while, but the author's lack of updates means the fandom is evaporating.) I worry that I'll never find another huge and thriving and engrossing fandom like HP; and I'm not sure what will happen then. Can I go back to small, disorganised fandoms? Can I manage without a steady stream of fic to rec? If so, I clearly can't be "a reccer" -- so what will I become? Will I ever be more than a lurker again, even if being an unknown reccer is only a slight step up? :D
