Publish some of your Perl code online. Establish a Wiki. Don’t ask anybody for permission - just do it. There will be chaos first, but order will emerge out of it eventually. And if not, Google and friends will like us better. ;-)
Rik van Riel of the Linux Kernel fame, told me and some IRC folks about a system which was written for internal use by Connectiva (his former workplace), that uses a DMoz-like category tree, where Slashdot-like comments are added. This sound like a nice integration of a few ideas. The Connectiva code is written in PHP and is not ready for release. Nevertheless, I think tweaking Slash to do just that should not be too hard, and may prove as a useful alternative or a complement to Wikis.
