If the Chatterbox title is a link to documentation about the chatterbox, users will expect the other sections' titles to be links to their documentation.

I find the Perl Monks site very usable: the main reason for that is its consistency. I disagree with knobunc that the title should be clickable.

Note: I'm not suggesting that users should ignore documentation. There is already a clear pointer to the chatterbox faq, but users ignore it. Modifying an interface that users frequently misunderstand is better than documenting the cause of that misunderstanding.
