I think what came across for me, other than that the author intended, was how unprofessionally the slush was handled.
Sorry, Birol, but for the first time in years I've got my bosses head on, and I'm hopping!
Business is business when all's said and done.
Firstly, I think we all agree that a sub is the equivalent to a job application. You don't give job applications to the office junior to open. The office junior couldn't spot the spot on her nose when she first starts work.
Secondly, if you aren't pulling anything out of the slush in six months, then close to subs. Why pay somebody to open it (which we have all heard is a long, time consuming and arduous job) therefore also costly, especially if you are getting NOTHING from it.
If you are occasionally pulling something out of the slush and it is worth your while but you are getting snowed under, temporarily close it while it's worked through and then re-open.
With regard to the author of the article, why mention it at all if it didn't fit the list etc? If I had somebody working on the slush for six months who didn't pull out anything and then found out something had been subsequently published, I'd fire them. No problem.
Don't get me wrong, I agree entirely that the slush has it's downside for both sides of the fence, but it is a potential source of profit, because if it wasn't then all publishers would close to it. As such it deserves the same professional treatment that publishers demand of the writers - because the loss could be to the company.
