Plus, I care. If the business I'm applying to for a job doesn't care, it'll probably reduce my interest in them.

Let me give you a strawman scenario: I walk into an interview at a startup that just landed its Series A round. I'm interviewing for a position as the chief products guy or the CTO or something. The interviewer across the table from me says "You spent a paragraph of your resume talking about the business you built from scratch into a $200k/year revenue source. That's not very interesting; let's talk about this cool IOCCC entry of yours from last year, instead."

I'm going to assume that the interviewer (likely the founder or a co-founder) is probably an idiot for dismissing a significant accomplishment of mine and focusing instead on something that is—relatively speaking—quite trivial, and that his priorities are totally off. My bozo bit's been flipped, and there's not a chance I'm going to want to work with this guy. He's going to spend the next 18 months burning KPCB's million-plus stake on architecture astronaut'ish goals that have nothing to do with solving real problems and making real money. I'm going to shake his hand, say 'no thanks,' walk out the door, and go have a pint. (bear in mind, this is a strawman).

Please note that I'm not a Perl guy, so I can't speak for you or Ingy dot Net or Larry Wall. I'm a 'business guy' who happens to have a Computer Science degree and writes his own code.
