UTD Site - "Home" Options

I don't know if this is the right place for this, but I have to say I'm a bit overwhelmed by the myriad drop-down options under the "Home" tab. There are six options which all seem to mean similar things to me:

Why UTD?
About
Ethos
Mission
Purpose
Philosophy

I can understand the different concepts in the context of what's posted in each section, but just looking at the headings gives me no real clue as to what I should expect to see there. Maybe it makes sense to compress these into a single "About" page, that can then address each subpoint?
