In my on going effort to provide Perl interfaces to lots of web services, I’m pleased to announce Chat::iFly. Using this module you can integrate iflychat.com (a web chat service) into your web site with relative ease.
A few years ago I wrote a little video game in Perl called Lacuna Expanse. Tens of thousands of people have played it, and while I wouldn’t call it a raging success, it has paid for itself and continues to make a modest profit. That said, it wouldn’t have if I hadn’t been willing to make drastic changes to the design of it way late in its development.
