It's interesting to see perly peeps justifying why they have or have not contributed to the Perl foundation. Peer pressure man, it's a force to be reckoned with.
You and you alone (hmm, well perhaps your significant other actually) know your financial situation. If you feel you cannot justify giving to the cause then that's your own business and you shouldn't have to explain it to others (whose business it is obviously not).
Just an observation.
And on a lighter note, hitting the old XMMS turntable today are:
Nitzer Ebb - Showtime
Sisters Of Mercy - First And Last And Always
Depeche Mode - Construction Time Again
Yazoo - Upstairs At Eric's
