Locus Magazine is the best-read trade-rag in science fiction. Every year they conduct the "Locus Poll" to pick the winners of the Locus Award (I won this last year in the best first novel category, for Down and Out in the Magic Kingdom) and to gather demographics on the changing readership for science fiction, fantasy and horror. The Locus Poll draws more voters than the Hugos, making it the largest popular vote on sf in the field.
The Locus Poll is now available online for all and sundry (though subscribers get an extra issue if they participate). There are a lot of sf readers in internetland who don't read Locus or self-identify as fans or industry people -- getting their input to the poll will be really useful and valuable.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
