I’m not sure what the rule should be in this case.
“Tyler Durden” is a pseudonym used by all posters at Zero Hedge. Pseudonyms, moms de plume, and moms de guerre aren’t usually quoted, in cases where the true identity is generally unknown. One writes of General Leclerc (nom de guerre of de Hauteclocque) of the Free French forces, not General “Leclerc”. Or in an extreme case, Mark Twain, not “ Mark Twain”, in spite of everyone knowing he was Sam Clemens.
It is rather confusing.
At that website, "he" is the pen name for a cadre of 20 or so different people who post articles on economic and political issues.
There is no single person who is "Tyler Durdan". "He" is a collection of people.
Not just FReepers. A while back I caught Mark Levin on the radio railing against "this bozo, Tyler Durden at Zerohedge". Mark, clearly didn't know anything about "Tyler" or the website. It wasn't but a few months later that Mark was actually praising the "good work" being done at Zerohedge.
Apparently someone cleared things up for him.
