The fact that it's Yaoi doesn't bother me... Most of the time it's mindless drivel. Like, "Sasuke is a gay male dancer in New York, Naruto isn't gay. But why does he find the Uchiha so appealing?" is the most common type of Sasu/Naru story out there. I personally don't like AU fics if there not in the actual Naruto world. In addition to this, there is essentially no foundation for Sasu/Naru... Sigh... But I guess that's why it's called fanfiction...
I know what you mean. There's this crud about MPREG ( I mean what the heck?) and other really unnessacary stuff like that. I doubt there's hardly any well done yaoi fics out there.
