This could be really neat, but showing me an ambiguous sampling of some ~250+ writers around the web isn't very helpful. In addition: most of the writer's have their email listed on the bio Pressfarm links directly too, so why would I pay for what I can already find?
There's a lot of potential here to be a helpful site for startups or independent creators, with a little fine-tuning I'd pay $9 just to access the list.
