You see, there are fandoms with limited characters, such us So Nyeo Shi Dae, Morning Musume and other groups that do not have hundred of members. You're only saying that because there are a lot of possibilities in the 48 group because there are a lot of members, and you want dynamics.
But that's just you being selfish with your opinions.
The fact is, most writers in this fanfic section commit 'cliche' plots. No matter who they use, if they are out of character (acting similar to someone not themselves) and the same concept is written over and over again I doubt you'd enjoy any.
You're being subjective instead of figurative, because your opinions are your wants and not what is really happening.
True, there may be too much atsumina, too much kojiyuu, too much mayuki, too much wmatsui and gekiblack and all that, but can you count on how many of them are 'original', 'unused', and most of all well written ? I'm not pointing out any names.
Everyone can improve as long as they continue to write, and I admit most of the fanfics now are pretty bad. Some are out of character, some doesn't use correct grammar, some even write in script form! (Acchan:, Takamina: yada yada yada). These are all bad, they're all literally but barely correct writing.
Reading other people's correct writing make people correct their own, this is why people should read ones that are well written.
But because of the demands of selfish people like you, the writers who write well have pretty much disappeared now, because this fandom really have selfish fans.
Well that's all.
1- I think it's a bit harsh to repeatedly call caghaunt "selfish". I understand an author's frustrations. I, too, have been inundated by requests from such "selfish" people. Yet, keep in mind their disadvantage and frustrations. You may like a popular pairing and so you have numerous stories available to you to read. A fan of a less popular OTP might be considered lucky to find just a couple stories to read.
If your OTP is underwritten and you come across an author whose writing you enjoy, I don't think it can be considered selfish of you to ask if he could write a story about your OTP. However, DO NOT bombard that author with requests. If he tells you no, simply accept it. If you're desperate, try to go one more step and write your own story about your OTP.
Keep in mind that authors tend to write about the pairings they enjoy. NO AUTHOR IS OBLIGATED TO DO OTHERWISE.
I didn't mind being called selfish and I had expected it will coming, because all the people could be called selfish at some point. I hope you didn't feel insulted with my opinion.
For me, all fandoms are full of possibilities when it comes to fanfiction. As for the fandoms of RPF (Real Person Fic), the possibilities is infinite. All could be written into fanfics. It didn't have a so-called "crack pair" or "crack fic". You (in general) couldn't really know what's going on in the reality.
For the Out of Character characterization, for RPF, there is no originality, especially when it comes to idols. They might as well act friendly or close to the others in front of the fans. But no one knows what is s/he thinks or feels in reality.
I didn't want to say a fic is "good" or "bad" as it depends on the person who read it. I didn't state any of the "mainstream" as it could be different for each person.
For "well-written" fics, have you read your own and call it "well-written"? Have you read others' and called it "well-written"? It's more subjective. When you read your own that the others said it was well-written, you might feel it isn't. When you read what the others said it isn't well-written, you might said it well-written.
Correct grammar. What is actually a correct grammar? When you spoke something (not in text) is it has a correct grammar? When you read something that you feel it didn't have a correct grammar did you actually think that the one who wrote it was still learning it or did it on purpose? Correct grammar is something you can't explain to. Correct grammar depends on where is the writer comes from. Let's take Singlish as example. Singaporeans used English as well as Malay and Mandarin. Their English is affected with Malay and Mandarin. They called it Singlish. Singlish didn't have what international called "correct grammar", so they separated it to "English (Singapore)". Just like "English (UK)" and "English (US)". So, no. There's no what was called as "correct grammar".
Read might as well help people to correct their own. But of course they didn't write it as the "formulas" for sentences stated like " S + Verb + Object + Adjective/dll". If they wrote like that, it's like writing something in their native language (if English isn't their first language) then translated it per words.
Demands or requests from readers, as Hitobo said, could always be ignored and continue writing as your own wish. The writers couldn't always stay in one fandom forever. They might have seems "disappear" because they didn't really following a fandom as much as when they first knew it. As time goes on, the fandom they knew has changed, made it difficult to follow it again. It's not always because of the readers.
Popular pairings are popular. I get it. But sometimes there are people who bumped into a pairing that isn't really new but has caught their interest and after some moments of following it, they decide to search for its fic. Not everyone who experienced that are lucky enough to found at least one fic about it. Even if they made one for themselves, isn't it quite awkward to spazz over your own? (Just like I wrote about SKE pair ShawAkarin (Hata Sawako/Suda Akari) but didn't feel any satisfaction when reading it).
"Fan Fiction Readers' Ethics".
-DO NOT repeatedly make requests of an author. "No means no."
-DO NOT pester an author to make updates. Contrary to what seems to be popular belief, writing a good story is not easy.
-DO NOT denounce a story simply because you do not like the pairing, setting, plot, etc. No one is forcing you to read it.
-DO leave positive messages. Constructive criticism is always welcome.
I agreed with this. Ever since I read and write fanfics I promise to myself to not forced any writers to update or continue their fic.
So please. If I ever do something like that, feel free to telling me via PM, tumblr, or twitter.
