DMOZ - The Open Directory and Perl
The Open Directory is still one of the sources search engines use to decide which hits might be more relevant. I recently looked at it and not only that I could not find Padre listed but I could not find any of the following:
Strawberry Perl for Windows, Moose YAPC::Europe, Bricolage CMS, PDL - Perl Data Language, SDL Perl and perl workshop only gave 2 real hits.
This is such an easy way to contribute to the Perl community. Anyone can pick one or more sub-categories within Computers:Programming:Languages:Perl or elsewhere, where it might be relevant, apply to become an editor and then start adding these sites.
