He attempted to cash in on the mISV thing. His book is still sold:
Micro-ISV: From Vision to Reality
It was published in 2006, is still on the first edition, and the last review attached to the book is from 2011. That gives a time frame.
I checked out his web site URL 47hats.com. It has reasonable article titles but is full of Greeking and looks like a spammer is squatting it.
mISV == dead, dead, dead
