If you follow @ProfJeffJarvis on Twitter, you know that he is a "thinkfluencer," which isn't a real word, nor is it a real Twitter account. Highly entertaining? Yes.
Apparently, Nassim Taleb, author of "The Black Swan," did not take the time to look at @ProfJeffJarvis's avatar (see:beer helmet) or read his biography. Closer inspection surely would have tipped him off that he was being goaded by a parody account.
