Nay to this. Every offtopic section I have seen on every forum I have participated in so far anywhere on the web has shown a tendency to grow like a tumour and take a life of its own. I would hate to see that happen here. I would be happy to see something like a PerlMonks sibling site for the offtopic needs of monks; it could be closely associated with PM (links, shared user database etc), but it should be clearly separate, not in-site.
