Male Or Female? (GenderAnalyzer)

GenderAnalyzer is a free site that seeks to automatically determine the sex of a particular blog's author. Simply submit a blog to the site and it will come back pretty quickly with a guess about the sex of the author. Overall the site claims about 66% accuracy. UClassify, the company that sponsors the site, also has a free service called TypeAnalyzer which determines something close to a Myers Briggs Personality Type automatically as well (though there are no accuracy statistics associated with this tool).

Analyzing distinct online characteristics for identity markers is rapidly becoming a robust business. Since so much activity online is either functionally anonymous or deliberately deceptive, everyone from advertisers to law enforcement professionals to national security types are trying to figure out who is doing/watching what.
