Hunkish blogging agent (Blagent) Nathan Bransford attempts to explain why you aren't getting published here. It's anybody's guess what the hell he's talking about. Here's a highlight:
"A week and a half ago I posted the query points system, in which one needs to score 10 points out of a 30 points system (Professionalism/Book Idea/Credentials) in order to get a manuscript requested. But what Conduit pointed out in the comments section is that the whole "resonance with agent" factor is extremely important and that there's an undefinable X Factor at play in queries."
Huh? Sometimes, the more they help, the more they don't.
