I think I like this dark background and light words. I spend a lot of time on the computer, punishing on the eyes, and this seems easy to read to me - plus the links are in orange so stand out very clearly; which is helpful, some readers hadn't realised the links were links, and the orange gives a better clue.
A drawback is that images with white surrounds look untidy now the background is not white - eg the graphic I put as the header and the changing sequence of book covers, darn it! Both tricky to work on!
What d'you think?
