Whenever I post something useful, I'll put it under Code Catacombs. If it's something not useful but fun or different, I'll post it under Cool Uses for Perl.
Expanding on your ideas, I'd like to see the Code Repository broken down into the existing areas as well as a few categories for Snippets (short, reusable code) and One-liners. I believe that having all the code-related material in one group, divided into specific areas would be the best way to organize.
