what's with all the gomers?

I am on a number of sites.  There is a Facebook page, a Twitter Account, and a Tumblr account, and in each place I will get the occasional question about the book.  This one came from Tumblr, where I tend to respond to all mail privately, as opposed to publishing things that might embarrass either the person asking, or me, for that matter.  What is with the different kinds of Gomers?

Okay, this one I promise will start to explain itself near the end of the second book, and will become painfully clear in the third one.  Each of the types is different, and each has a role to play.  I will say they are related, and the answer is a lot creepier than any of us would like to imagine.  Then again, I imagined it, so who knows.
