Something that makes me always just go to dev.mysql.com or php.net for documentation is the user comments. sometimes you just find some real jems that are really worth reading.

It would be great if this somehow could get integrated into the (offline) help system in GNOME could somehow have this stuff integrated. maybe some AJAX foo to fetch comments from the Interweb if you’re connected. So then you get the best of three worlds: good graphical documentation interface, good documentation and user comments to the docs!
