I don't know, fan-fiction can actually be good. I know, I know, this is the part where I get stoned to death, but hear me out. I'm not saying all of it is good, or even half is, or even .000001% of it is even good, so, yea. What I am saying is that .0000001% that is actually good? It's pretty dang good and worth a read almost every time.
My secret to finding the good and avoiding the bad? Have a friend that reads fan-fiction, let him go out and look for the good among the seas of eye-gouging hell, and enjoy when he finds it and links me to it. Yea, I'm kinda an ass, but I haven't read anything that's made me want to tear my eyes out for at least a year now because of it.
