The only thing it is lacking is verifiability, and in many cases this is an asset not a detriment. When things are easy, cheap and fast you can crowd source verification so that if someone tweets out, "The rioters at $local_location have turned violent and are burning down the $city", everyone there can verify this and drown out the propaganda and rumors relatively quickly.
So the first part of his statement isn't so much of a surprise. It's like saying, "The next political revolution will take advantage of electricity." It's very obvious.
So really, what we are evaluating is can they predict unrest in Egypt reliably using Twitter and tweet content. I believe it's possible. Take for example, that calmness can predict the stock market[1]. Or pronouns can be used to predict any number of things[2]. Is it possible that the CIA can watch for shifts in calmness to anxiety or shifts in the number of pronouns used in reference to a particular leader and measure the likely hood of political uprising? That seams plausible to me.

I felt like Naquin was circle jerking with what he was doing, the article gave the distinct feeling that Naquin thinks he can predict the events of the future, just not the when.
