Markdown and stuff

A while back, I was messing around with the typography of the site and then I guess I just forgot about it.  Anyway, as I started integrating a blog post, I resurrected it.

This is one man's opinion of improving a few things, but I promise *not* to be hurt if no one likes this and the currently look-and-feel remains.  This was not a ton of work on my part, but in case anyone likes it.

Basic goal was to create more contrast with the various elements.

Also includes specifying redcarpet, which doesn't seem to have a problem with UTF-8 like maruku does.
