I can't read the page properly (using IE) as font-size keep getting HUGE due to minor HTML error.
The error is in <h2> part, where closing element is not specified (see below):
<h2>About<h2> <--- Element is not closed, but nested.
And because "h2" has a font-size of "140%" in CSS, font-size just keeps getting HUGE as I go down the sections.
Only IE seems to behave this way, but nevertheless, I think it's a good idea to fix the page.
