Dropdown menus don't render well at all on mobile phones (and I run this site from my phone 50% of the time!). Not that it matters, but I'm also pretty sure that person was an Isis sock puppet. Only ever posts on Isis' blog and didn't stop by or e-mail me his/her suggestions when I reached out.

Anyway, if you can think of a better navigation layout that doesn't require dropdowns, I'll try to figure out how to implement it.
