I like the idea of a lounge.
As far as the design, making it friendly for people with vision issues (even just due to age -- for peeps over 40), keeping it relatively simple to use and lots of nice high contrast. High contrast for people with vision problems can be helpful. I had eye surgery about 10 years ago, and have had some contrast issues since, and even though still quite young had to wear reading glasses. High contrast sites help me a lot without struggling.
You are probably totally on top of that though. This current site is simple enough with high contrast. No complaints here.
