I was put onto this through the Pharyngula site. The "histomap" has absolutely no connection (certainly no logical connection) to "history." A vague sense of "importance" that is not only thoroughly subjective, but quite incalculable is used to "map" the relative relevance of various . . . what? Regions of the world? Cultures? Races?The altogether positive reviews are obviously by idiots who--insofar as they use this to teach history (!!!)--are doing massive harm to younger generations.
