I went to http://stackexchange.com/ to see what was there and whats changed.
And so I click Learn More... which takes me to http://stackexchange.com/about
And there's Joel glaring, and Jeff being very happy... and David looking not angry. But this really doesn't tell me what Stack Exchange is about or any bit about how to learn more about Stack Exchange.
I was kind of expecting a tour of the site... not the staff.
Consider linking 'Learn more' to http://stackexchange.com/tour instead.
