That must be a reply to Scott McCloud's "Reinventing Comics". It came out July 25, 2000 and this strip is from June 22, 2001 (under a year later). One part of the book was about micropayments.
Edit: oh yeah, obviously it is. The character talking is Scott McCloud's character, and it's titled "I can't stop talking" and Scott's webcomic at the time was called "I can't stop thinking".
In fact they must be replies to these posts (comics) from June 2001 about micropayments:
I guess attention spans have shrunk or I’m less tolerant of another ‘some guys opinion’ now they are spouted at me 24/7 or it’s the fact that there’s more than six webcomics to read.
Can’t imagine this comic being very successful nowadays.
Having said all that he was being mocked contemporaneously so it’s not just me!
