The only obvious thing I see wrong with the page is he isn't escaping quotation marks in his title attributes with " causing them to be malformed. His copy of jquery 1.7.1 doesn't match the copy I found here but I'm not sure if that's cause for alarm.
I'm not entirely sure what those things mean, but I will definitely investigate. I notice my hosting service (BlueHost) was down today, I assumed doing some upgrades or a reboot.
Update: Fixed. The bad jquery was from a bad wordpress plugin. It's gone now!
Quite a few of us are working on interesting projects; many of those are solo, but some could maybe use some help. So here's the place to ask!
