There's this now....

M Brane SF Quarterly #4 is for sale now on Amazon. Two hundred forty pages of some of the hottest new SF, the final batch from M Brane. Some great stories in here, including one I particularly enjoyed called "Stumptown Physics: Toward a Unified Theory of Infinite Probability Amplitudes, Elective Affinity, and Amanda Palmer" by Travis King. Also the intriguing "A Second Enchanted Evening" by Mary E. Lowd. And the quirky  "The Vitruvius Project" by Robert Drake.
Also, one of mine made it in too.
A fresh appraoch from some new voices, if you care about well written sci-fi, pick up a copy.
