Dear Miss Snark,
Reading your blog is a thoroughly pleasurable experience, for which I thank you, but I can't help feeling like a masochist when I catch myself clicking onto your URL. Don't you feel like you're giving a lot of these very misguided aspirants false hope by indulging them? 98% can't even write a query--how do the expect to revise MSS?
Giving people tools to improve isn't false hope.
Giving people information isn't false hope.
Get your head out of your *. Great writers don't spring from the womb fully formed, clutching a thesaurus and a publishing contract; they learned how the industry worked and practiced a lot.
