Oh, a more advanced tweak that I've only seen on a couple pages would be to take your vertical sections (about, intro, blog, those) and give them their own horizontal scrolling sections with left and right arrows.

That could easily turn into a significant time investment (a day or two, if you're a motivated beginner with some knowledge), depending on your current skill level, but it amounts to a few very wide <div>'s, and some jQuery to calculate scroll distances. It'll make your page easier to read, and more visually complex in a good way.
