I've been writing and submitting since 2006. I created an account in Duotrope and logged in my first sub on July 13th 2006. By that time, I'd been subbing for a few months and had sold my first story to Strange Horizons so the stats here are skewed. My 200th submission (to ASIM) came back rejected on December 16th. Anyway, in case anyone is interested, here's some juicy bits of statistical nonsense I thought I'd share.
200 subs, 17 accepted pieces, that's an 8.5% acceptance rate, assuming that all 6 of my pending subs gets rejected. Of course, many of those pieces were subbed multiple times before being accepted and some of them are reprints which get counted several times. I told you the data was wrong!
A total of 12 different markets bought my stories. One market bought 3 stories, 3 markets bought 2 and the rest bought one each. Six of these stories were (or will be) published online only, 7 went to print markets (these may have online pdf copies available, but they're considered mainly print mags) and 4 went to markets like Shimmer who favor neither print nor e-formats but offer both.
Three stories were sold in 2006, seven in 2007 and six in 2008 which shows just how little I've been writing in 2008 (new job, new home, new life basically).
I don't know how useful any of this is, but here you go, my end-of-two-years stats. Enjoy.
