Aw, thanks. :)

But what does "fluff" mean to you, or is there really a generally-accepted definition?

I hope there isn't. Basically I just mean... you know, I don't really have anything against fluff as such, as in feel-good stories that don't try to do anything but entertain. But I always prefer it myself when there's something more to it as well, even if you don't have to notice it to get something out of it. I guess I just like chocolate chip ice cream more than plain vanilla.
