That doesn't mean that there aren't valuable lessons to learn from non-web startups. This is what I took away from the post:

1. A small niche market can be profitable (maybe not Facebook-profitable, but a good living nontheless).

2. There may be a lot of non-web startups out there that need online services of some kind - advertising/marketing, contact and booking management, whatever.

3. There are always profitable opportunities if you are prepared to do things others are unwilling or unable to do.
