Just thought I'd provide a link to my delicious bookmarks to our listeners in case you wanted to see what I find as soon as I find it or browse what I've already bookmarked. Everything in my list has some educational focus and I tag all of them.
Give it a gander.
Oh, by the way, the apostrophe in this post title indicates possession, not the contraction for "Jeff is.".I could see how that might change the meaning significantly and be rather embarrassing for yours truly.
