Some do it for love some for money.
I'd blame it on the easy target of management. My managers don't understand what I do so can't determine how well I'm doing it. They do not give any recognition for quality or skill just time served and conformity.

If they had you working in teams possibly extreme programming everyone would learn from you and possibly attain your level of zen. It sounds like you want to share your wisdom and as the man above says perlmonks is a fine place to do it. But your guru status should also be officially recognised through promotion. Training and assesment of your peers would't go amiss either.

The problem with Perl your collegues are having is it's so easy to find a way to do something but very hard to find the best way without a little motivation. If however you have truely mastered Perl to a Larry standard and love OO why don't you move on to something 'harder' like C++ or Java :)
