Addendum to my Blog Comment post below...
Just wanted to say that I posted the full text of my Tametheweb blog comment here on our blog, because I discovered after posting my comment the Tametheweb blog yesterday that the blog owner has to approve my post before he'll allow it to appear on his site. So just in case that doesn't come to pass before class today, I just copied my comment within our blog and included a link to the Tametheweb blog. Thanks!
