I'm not commenting on the article its self, but I liked this snippet:

"I’m the 1% of tech users. I know 99 other people out of 100 (close friends and relatives) that I could never get them to use the Oink app, Foursquare, or buy from Fab.com.

People need to build for the 99%."

Absolutely. There are so many opportunities solving problems outside the world of software with software. Unfortunately it's pretty hard to see and understand those opportunities when you only live in one domain (for most of us here that is software).
