So his only argument that Twitter is a protocol is that Seth Godin said that Twitter is a protocol. I think there is some truth to it, but it is nowhere near the level of information control that Google has achieved with Search. It's an invalid comparison, especially since 99% of apps operating on the Twitter protocol are completely asinine.

The mobile payment angle could be true, but its far from a sure thing. I tend to think most payments from mobile devices will be done through mobile web browsers, the same way we do them on a computer.

The piece closes by saying "The true power behind popular protocols can almost never be predicted" and "as Twitter grows it will have to remain observant of emerging trends of its users".

So you write an article predicting twitter will be a cash cow, and conclude by claiming the method of generating cash cannot be predicted? What makes this cash cow such a sure thing?

I strongly believe that Twitter will succeed, but this article is weak. The only real nugget is the Amazon Affiliate angle, and changing user links is borderline unethical and likely not a massive revenue generator.
