Over at SFSignal there is a Mind Meld in which I took part. If you are interested in this question thrown out to writers: "Once upon a time, sf/f was full of taboos: no swearing, no sex, etc. We're thankfully past those days, but are there any taboos still remaining or new ones that have sprung up? Have you ever had trouble with publishing something, or caught yourself self-censoring?" then take a look.
Authors taking part include Neil Asher, Anna Tambour, Margo Lanagan, Peter Watts, Steve Aylett, Kristin Kathryn Rusch, Ellen Kuschner, etc.
