An accessible information referral site for aging Americans

I came across an article in the NY Times about, a referral service from the National Council on the Aging. This looked to me like a good example of appropriate design for a well targetted audience. The text is large and easy to read. The navigation takes a linear approach if you skip the global navigation at the top and follow the "Let's get started" link on the bottom of the page after the introductory text on the front. There were a few things I found could be modified to make the site more user-friendly for this audience. I thought the top portion of the site -- the global nav and sponsor icons -- took up way too much screen real estate. When I load it into a 640x480 resolution monitor, only the first 2 lines of text appeared, with the screen dominated by logos. (TIP: A good way to check at 640x480 without changing your screen resolution is to use Porter Glendenning's 640x480 screen test.) It would be nicer to move the logos to the bottom of the screen and to either duplicate the "Let's get started" link in the global nav or somehow minimize the importance of the global nav, because use of the site doesn't start until you click "Let's get started". The global nav links to content that is really just metainformation -- information about the site. I also have to note that when I looked under the hood, I expected to see H1 tags for the headings, but instead saw the font being controlled by HTML font tags. I admit that I commit the sin of using CSS and HTML font tags myself rather than using the H# tags, but for this audience, I would expect a large portion of the audience could include people using screen readers. Overall, this was an appropriate design that could be made more accessible with some minor adjustments. I don't often throw my $.02 up about site designs, but am interested in the topic of accessbility, so this site was a good exercise.
