Inaccessible websites?

[denise]

I'm doing a talk on web accessibility at LinuxConf Australia and would like to give specific examples!

So, gimme your best examples of websites with specific accessibility problems that drive you nuts. Use of tabular data where it doesn't make any sense, sites with horrible contrast or that won't let you change font sizes, restaurant websites that are entirely flash-based, etc, etc.

Also, if anybody knows of good illustrative videos of a) people listening to a screenreader and b) people dictating to their computer, point me at 'em?
