His only mention of MSP is from Nov, 2000 when he discovered the term. And he talks about ASPs as well. I had started my first of both, over a hear before he heard the terms :)
It really was a new term at the time. But he acts like the concept was new. It was very tried and true in the 1990s. It's an ancient article, just funny that in late 2000 he was thinking that MSPs were some hot, new thing, lol.
