Via Galleycat I have discovered Redroom.com, which bills itself as a social networking site for authors and “the official home of the world’s greatest writers”. Of course it isn’t only for authors – readers are welcome too. So basically the idea seems to be that it is a bit like SFFnet – you want to be online, they do all the tech for you.
Given that it is a mainstream literary thing, I’m afraid I assumed the worst. But I went to have a look, and lo, there were sections on SF and fantasy writers. I didn’t recognize many of the names, but there weren’t many people there. A quick word of congratulations to Jason Erik Lundberg for being the first person to be listed as a writer of “speculative fiction”.
Anyway, these folks are based in San Francisco, and of course the web site is accessible from anywhere. I shall see what else I can find out.
