My momma taught me proper manners, how to say please and thank you, but outside of a small circle of friends and fellow writers, I haven't made a habit of telling other writers I appreciate their work. Not that I don't appreciate it, but it hasn't occurred to me until recently that it's important to let that appreciation be known. I've been making an effort.
A couple guys whose recent science fiction stories have caught my attention are Mike Duran and George Walker, authors of "Father Fayad's Curious Compatability Projector" and "No Remorse" respectively, both stories available at Ray Gun Revival. (Duran's story is the second in Issue 48, and Walker's is available in Issue 50.)
Another writer, M.L. Archer, has a thought-provoking story up at Perpetual Magazine--"We can do it"--a scary and not-so-futuristic vision.
"The Mark" by Jade Smith is a vampire tale that I actually enjoyed, and "On Becoming a Cyborg" is an excellent poem by John Nichols. Both can be read over at Fear and Trembling Magazine.
