Everyone missing the obvious thing here. It's not about the parrot site at all. It's about Cringely's site. Cringely has written a post about how to make a lot of money doing something easy. Cringely's post gets a lot of traffic. (Currently #1 on HN.) Cringely's site hosts ads. Cringely (and Mrs. Cringely) make lots of money. The parrot site is to Cringely's site what parrots are to the parrot site.
His traffic has come up sharply over the last few months (Quantcast: http://www.quantcast.com/cringely.com) to ~3k/month. Compare with ParrotSecrets.com at ~13k. Cringely is just following his own advice. What he's doing is as interesting as what he's saying.
