I'm a reader not a writter. I cannot come with a structured story, just bit of thigs that won't get together.
After something like 4 years of lurking here, I finally got an account !! Finally I'll be able to collect my fav stories.
Things that currently annoy me in fanfics :
Summaries full of spelling mistakes. If you cannot write such a short piece of text without those, then I presume your story is unreadable, and I won't even click on the link.
Summaries written in caplocks. Seriously it's so retarded, it makes the author sounds like some sort of shouting hyperactive brat.
Canon Sue. Mary Sue are bad, but canon Sue are worse. I really don't like it when a character I like is turned in a super idealized beautiful perfect angel everyone like and blabla. It makes me puke. Some people need to understand that flaws are what make a character entertaining, and that being loved by anyone is neither realistic nor interesting. It's just annoying.
I also hate when the character names aren't spelled properly.
Teen pergnancy fics. WTF !!! There is nothing desirable about it, but apparently the immature female teens who make the majority of writters on the Naruto part of ff.net thinks it is. It's diheartening.
I never flame, even if it really tempts me reading some of the gabage stocked her. I'm well aware most writters are really young and that they will probabely improve if let the oportuny of. I'm not going to shatter their fragile self confidence even if their story sucks. I'm not paying for it and they guenuinely share it, they aren't doing anything wrong, they are just lacking talent.
