Stuff I'd like to see more often in fandom?
Well, less m?mes, obviously. And less stupid nicknames for characters. I'm tired of seeing Cirno being constantly called "nineball", or utsuho "unyuuball", or Meiling "who-the-heck-is-that-girl" or Mima "she'll-be-in-the-next-one".
And also, I'd like to see more complicated plots. Quite often, in doujins, I feel like there's an unspoken "let the characters like you found them" rule. In other words, no matter what happens in the doujin, everything has to be back to normal at the end. And that annoys me, because if there's no change, then what's the point in reading the whole thing to begin with?
I am aware that a good artist is probably not a good writer (given how ZUN handed the Watatsukis' huge curbstomp battle of Touhou's main characters -and that's considering that ZUN is a good artist, but I'm derailing), but sometimes, I'd like something else than "Reimu go to the supermarket. Reimu buys an apple. OH NO, REIMU HAS NO MONEY! Reimu flees with the apple. Stuff happens. Reimu doesn't get the apple. The end." I'm also aware that most touhous are allergic to original characters, but when I read the doujin Re-Take, I usually think "damn that's hot!" and then I start thinking "why don't we have something that good? Is it because touhou isn't as LOL DEEP as Evangelion? Why does the chicken cross the road? Why so much hate toward the Watatsukis?" and then I stop thinking and I go play Fallout and punch supermutants in the face, but that's another story and that doesn't interest you.
My point is that, in touhou fanworks, I sometimes would like to read something else than childish doujins. I'm not saying I want some kind of David Lynch/Touhou cross-over (actually, that sounds awesome), but sometimes, I'd like to read something that doesn't feel like it's been written on toilet paper while the artist was taking a crap.
And also, I'd like to have more moonboobs, because they're great.
