This entry was published at least two years ago (originally posted on March 18, 2003). Since that time the information may have become outdated or my beliefs may have changed (in general, assume a more open and liberal current viewpoint). A fuller disclaimer is available.
A ton of useful (and fun, in an extremely geeky sort of way) bookmarklets for digging into the code of a website to figure out just how it all works: Accessibility-checking favelets. I’ve snagged the first two listed already (‘Show and label divs with ids’ and ‘Show and label divs with classes’), and will be checking out more later on.
Geek toys!
