Just to be really unhelpful, I've actually only written 5 short stories over as the last 2 years, 2 of which are maybe passably ok ...
I'm much more interested in novel-length stuff, but I don't dare put that on the web, cos of the problems with publishers getting shirty about prior publication. (For me poetry was a bit of an accident, but it's so addictive! Beware: one day you may wake up with a dreadful urge to spout; scary though the prospect may be, it cannot be denied.)
The good thing about the web is making wonderful contacts whom one can then abuse by sending them chapters for crit (thanks, James, Perry). The WD groups are a much better bet for good crits than the open forum, I agree.
What kind of market are you sending your stories to? Have you had much luck? I was lucky with a short story for a live reading sponsored by the W Midlands Arts Council ('Short Cuts' at the B'ham mac). Worth checking that kind of thing out on the web. They also do a local magazine, 'raw edge' in our area.
I started moderating this forum in the hope that I might feel like writing more short stories, but luckily I really enjoy reading and critting - and the flash sessions are good excercise. http://forums.mosaicmusings.net/cgi-bin....SF;f=18
