I've started posting on Nifty again. So I was convinced really. And, if you're not at all looking to publish any gay fiction that you're currently writing, but want readers to sit down and read you.. you have nothing to lose. Its the ones that will publish - eventually, that probably need to stick with GA.
And I think if you're certainly going to try and publish a story you're currently working on, I wouldn't post it anywhere. Gay fiction isn't going to be picked up by mainstream publishers anyway (Unless its just that damn good). They're going to be looking for best sellers and there's not really a market out there big enough to support gay fiction (in their eyes), so a publisher probably will decline you IF you've posted on the web. The whole why should we pay for something that we can get for free, concept.
