When I posted the original article "Critical Fault: Twitter's Sentiment Paradox" I sent it to a colleague I respect, who in turn forwarded it to one of his colleagues he respects, who wrote: "My quick opinion is that I don't buy it, I'm afraid. Sorry, Sid." he followed, speaking of the Twitter sentiment analysis companies as "people I don't think deserve to be called Charlatans." And He's right. I called the entire field charlatans. He sent me a couple links to companies that it would be mean spirited to throw in with the bad guys. So I have some apologizing and retracting to do.
