There's an excellent article available on the Intarwebs (fount of all knowledge and wisdom, except for Wikipedia, which is right about a third of the time) called A Group is its own Worst Enemy, by a wise and learned gentleman named Clay Shirky. Go ahead and read it now, because I'm going to be pulling a couple of things from it to illustrate why internet, e-mail, and list dynamics can be astoundingly harmful to the well-being of the members of the SCA, and how circumventing this cycle reduces the amount of Drama Llama poop being flung about at any given moment.
Go ahead, read it. I'll wait. It's an excellent article. It's about much more than my little idea today.
