One thing you might really consider doing is posting a request for feedback and opinion at the end or the beginning of the story.
I've posted a lot of stuff at Literotica.com, which has an awful lot of members. Still, only about 0.1% (one out of a thousand) bother to vote on a story, and in my own experience a story will generate maybe 2-5 pieces of real feedback before it sinks beneath the waves.
If not that, then maybe we should consider posting a sticky or creating another board where authors can specifically ask for feedback and stories can be discussed. Or you can always ask me. I'm pretty tough, but I'm fair too, and I like reviewing stories.
