Remember Ruby on Rails? Six years ago it was a bit of code a couple of people the nascent Ruby community had heard about. Five and a half years ago, it was a screencast. Then the really good Java programmers realized that maybe programmers don't have to write XML all day to get things done.
Don't discount the possibility of bragging a little.
I've built a few of my own projects with Perl. Some of them you've seen. Some of them you haven't.
Why do people get excited when they hear that JT Smith and crew built The Lacuna Expanse with Perl, or that Gabriel Weinberg runs Duck Duck Go with Perl? I think we like seeing technologies we enjoy using and building and recommending used productively and effectively.
(Perl touches almost everything in my business, Onyx Neon Publishing, from managing financial matters to editing and formatting to running our website.)
Why not brag a little bit more? If you've built something—especially if that something brings in money or prestige or whatever reward—show it off.
