Well, as you can see, the embedded YouTube video takes up more space than is allotted in the template. I guess those things don't automatically scale down to the available space.
I'm still new at this thing (that's why my blog isn't nearly as pretty as some of the experience folks'!).
Speaking of experienced folks, one of the Pyromaniacs has taken over an old blog titled, The Calvinist Gadfly. This looks like an experiment itself, but a promising one. I'd recommend signing up because I have a feeling it will be an interesting and fun experience watching the thing morph into whatever it will become.
