the person you are talking to is taleb himself. he pops up all over the internet when he is criticized and gives these very... terse responses.
I put my foot in my mouth all the time, but I put my name to it. Taleb is interesting. Are you saying that the other account is literally Taleb, and that he's known for astroturfing campaigns? I wouldn't discard such a proposition, but I'd prefer hearing it from someone non-anonymous.
(For all I know, you're just an account created to extend the thread.)
