For one thing, it brings on the spot critiquing by editors and agents. For $40, I can give 5 pages to a professional to read and give me feedback on. It's both exciting and scary. I have been rejected before, but never face to face. I have gone through workshops (which I love and miss), but these are people who do this on a regular basis and professionally. These are the people who can truly decide whether I have what it takes to become a published author. It's quite scary to think that I've spent decade of my life do something I really wasn't good at. Granted it's one persons opinion and I know that I will always continue to write even for myself and no one else, but still.
I'll let you know if I do it. I will also continue to blog from deep inside the conference. It is why I got the tablet, right?
