Metacrap: Putting the torch to seven straw-men of the meta-utopia (by Cory Doctorow). The seven reasons why meta-data is doomed.
Here in the Info-Ivory-Tower, we understand the importance of creating and maintaining excellent metadata for our information.
But info-civilians are remarkably cavalier about their information. ... This laziness is bottomless. No amount of ease-of-use will end it. ...

Accessibility evaluation practices - survey results (Dey Alexander). My gut feeling is that until we have serious AI, only a human will be able to adequately evaluate a page's accessibility. This survey provides data showing that's how most people evaluate pages, so I guess most people agree.
While you're there, you may be interested in the Web accessibility podGuide (an alternative to the Westciv one which did the rounds). I'd love to be using this, of course; anyone got an iPod they'd like to donate? ;)
