Well, and here's the thing. Some people don't improve, for whatever reasons. You have been. Really fast. So much so that I will gamble and say when 2012 rolls around, and you look back, you will see marked difference in your craft.

Another thing, I keep trying to figure out how to start a crit community. The thing that holds me back is the usual stuff: nobody wants to spend their time monitoring it, yet who's to see that members aren't just demanding crits but not offering them, and checking to make sure the crits aren't 1) sloppy or 2) irritating rewrites of your material, rather than discussions and reactions.
