After wrestling over whether we wanted the blog to be merely informative or interactive, after hearing from several of you, we've decided to move to the more interactive format.  Our only hesitation was the time required to moderate, but after several discussions we've agreed to begin posting and responding to comments as they come in.

 So join in our discussions when you have questions or comments!  I'll be posting a few that are currently in queue today.  Thanks for reading and for your interest in discussing!
