Brian,
Not that you asked, but the "guest speaker" IMHO should down with the featured articles if it is not going to get posted too very often etc, and keep it in the more true learning article area. I can see why you might want to leave it above........but, below still seems a better fit. My .01 of course.
To a degree I too like the "G&M" higher up in the list too. L&A could go lower IMHO too! for my second .01
my .02 total!
