If you're really interested in contributing to the Perl community, there are plenty of ways to do it without actually crafting your own CPAN module. Unless you really have an innovative package that the world is clamoring for, what's the point? Instead, here are some ideas:

• Review others' work, submit patches for bugs/perldoc enhancements, etc.
• Tutor new monks in the art of proper namespace usage
• Understand the apocalypse

If you insist on making your mark in CPAN, focus on existing modules that might interest you. For example, I've always wanted to enhance some of the *::SSH::* modules out there. Granted, I've never had the time to start that project, but it would be a better use of my time and skills than trying to create a new module that nobody would really use.
