Good advice, but certainly common sense. Startups that rely on others are destined to fail.

Using AdSense (or any such mundane scheme) is a sad excuse for lacking the creativity to develop an innovative revenue model that fits your startup and the values of the user community.

Piggybacking on facebook? Don't even get me started with that one; that's a another whole world of problems.

Not selling is not an 'independence' strategy. It's just a gamble that your competition won't wipe you out before you get sold...

Either that, or a gamble that your business model is capable of producing... gasp... profits.

Yes, that's the other case.
