'any chapped ass monkey can start a story; it's finishing it that's hard'
Pardon me whilst I munch my banana. Not much of a writer, but I'm a fanatic fanfic reader, at least in the HP universe. I've also recently discovered that I enjoy doing beta work for authors, so hopefully I can give back a bit to the community in that fashion.
One thing I have tried to do is capture what I think are the best stories and writers in my favorites list. If you know of something I've missed and really must read, please PM me!
In terms of finding stories to read, I locate them almost exclusively from the favorites lists of writers I like, so I usually have five or more author pages open at any given time as I work my way through. I never cease being amazed at the sheer talent of some of the writers I've discovered here, so if you're one of them and are reading this you have my gratitude and admiration!
THOUGHTS ON WHAT MAKES A GREAT STORY
I can go about anywhere an author wants to take me, but please, remember you are starting from a point of canon when you write fanfic. The further from that you wish to diverge as an author, the more important it is that you set the foundation for that divergence. A couple sentences that create a new universe won't cut it. If you have to write a wildly different AU, show the reader how you got there. Especially true in character development. People can change radically, but that change comes as the result of something rather than out of the blue. It doesn't matter whether the change is of relationships, orientation, attitude, ability or something else. Change does not occur without a catalyst, and if you're not writing about change, you are not telling a story. That's what it's all about.
