Agreed on the Engineering Statistics Handbook, especially Section 5 on Process Improvement, which contains a decent (and free) treatment of Design of Experiments. A lot of the earlier sections are ok but not as sharply interesting, but their DoE stuff is quite good.
I disagree. Browser side user-css files are the solution to this 'problem' (honestly, my main gripe is low contrast, mainly the gray on white that is the last fashion these days)
opera is the only one that got it right. easy to write the css in a way it works for most sites, and a very convenient way to turn it on/off. too bad opera is ridden with bugs since 8.5 and so i gave up.
Anyways, it's just a width, line-height, font changes. Just to show a little bit of CSS could have helped and is just for the homepage. Could make a custom css for it, if you want. The site is immensely useful, though.
