I think that IBM Watson expects a general text no? I admit to having done some personality classification on OKC profiles (around 200) and found that disproportionately to the average population, there were a lot of people that were classified as caring, helpful, social, popular individuals.

It fits the medium. Just like one would expect HN comments to be full of more "head-y" discussions.

I'd assume that this might be the same algorithm, but I'm not really sure of that.
