Jetse analyses the Interzone slushpile for May, saying what worked for him and what didn't. Interesting reading.
For the record, I sent a near furture post catastrophe quantum computer story, which Jetse said "...while "Reboot" is a very good story, it still did not stand out enough for me to lift it from the slushpile". Which actually makes me feel quite good (a rejection with praise is surely the best type of rejection!).
