You may or may not find this relevant.
The first thing I noticed is that there is no "About" page. I couldn't find any information about Manifesto Games and what they do, their purpose, goal, etc.
Again, you may or may not have a requirement for something like this. But I found it very hard to find out the purpose of the site. It may be obvious to some, but you know what they say about assumptions.
Well.... Corporate, perhaps.
But I take your point. Johnny's supposed to be working up a "soapbox" piece at the moment which will be more genial and less confrontational than I typically tend to be, and explain why gamers should find us interesting. (me=aggressive New York asshole, Johnny=kindly Baptist minister -- a match made in, ah... well, somewhere) But that might serve the purpose.
IMHO, the "corporate" or (more in-theme entitled "about") should go to the, bare with me, left of the "home" at the top.
Personally, I would go with "corporate" at buttom being a strict corporate info and then the "about" at top being more loosely self-description and goal statement and the on going "whinery" *ahem* I mean "take" on the industry and all that good stuff and why it need change and how manifesto can fullfil it (and get some investors a nice income on the side) and so on and so forth.
(My apologies for the insult-jests at your expense. =P)
