I know I've mentioned this site a few times (probably because I'm so impressed with it) but I want to encourage everyone once again to go check out On Fiction Writing, a wonderful on-line writing community that has improving my quality of life ten fold!
OFW has weekly author interviews, regular features with tips and techniques to improve your writing, book reviews, flash fiction, and my personal favorite, the opportunity for critique from fellow writers. Check out the in the Agora section to post query letters and synopses for critique or head over to the Workshops page to post chapters and short stories and to review what others have submitted. Nothing helps your own writing quite like critiquing others, believe me.
AND, for a limited time (not really) I have a robot-centric sci-fi short story up for review that I would love for anyone and everyone to tear apart.
So go to OFW, get involved in the writing community, and critique my story!
