A "gopher:" link came up as a joke in one of the IRC channels. So I wanted to see if Firefox still groks gopher links. It does. And I found Veronica. And typed Perl. And one of the first three hits has PDFs of Learning Perl, Programming Perl, and Advanced Perl Programming. Hint: those are pirated.
So, now I get to email infringement@oreilly.com to request a takedown notice... on a gopher site!
