Wouldn't we all like to know what literary agents are really thinking? Mine is always so nice to me, I sometimes suspect he's protecting me from harsh reality. The agent of a friend of mine, on the other hand, is so blunt with her that, if he were my own agent, I would probably turn up my toes and quit writing forever.
A colleague turned me on to the fun and funny blog of an agent in Colorado. Since Miss Snark quit blogging, it's great to see an agent giving us a glimpse of how she thinks. Lately she's been blogging about what editors want--and don't want--and I think it's really helpful. You can visit Kristin at http://pubrants.blogspot.com/
