There's one thing that might make people think twice about what they're doing - putting lots of scenes of their own novels onto the internet for others to read. Anyone could be reading them and then taking their ideas for their own works, couldn't they. I've got old part-chapters of some of my own work on my website, but never enough to get the whole story out there, there's much more background to my own than seems from my excerpts. Saying that though, when I was telling a lot of my story, via query hell on here, it made me quite nervous telling so much about the plot
Reading what the Scott girl said, it seems quite plausible to me, she was 14 or 15 years old and writing a story that suited that age group and putting it onto the net. Then some middle-aged woman comes along and makes a bomb about teenage vampires. It certainly makes me think twice about it.
Then there all those ridiculous little Twilight readers having hissy fits about Scott on the comments part.

She's a very pretty girl too, so I suspect a little jealousy sneaks in there also.
