Some of it is dreck, of course, but some of it is surprisingly good. There are a lot of fan-written stories that are better than many of the Season 3 episodes... Some fan fiction is just adventures, as if they were new episodes, some is relationship fiction, and some is porn.
Yes, thanks, I will check some out. I mean, I've read Star Wars and Farscape fanfic years ago but not much in the way of Trek for some reason. I think it's because there are so many movies and episodes that I forget what happened in most of them, and I just go back and re-watch stuff again instead. I read the official books sometimes also.
