The problem with doing something commonplace is that it's already been done. I love the idea of open-source, so I'd love to help. Although I only installed Perl literally a few days ago, so I won't be much help up front until I get the hang of it or am inspired to actually do anything with it.

There's really nothing I can think of that hasn't been done (including open-source) - especially that's commonplace - so I have no suggestions. But I'll be willing to help. I'd probably come in most handy in converting codes from other languages to Perl.

Probably something that interacts with websites automatically would be an easy suggestion.
