Is Kanban used as a buzz word?

I read today a good post from David J Anderson. Minutes after I read another one where actually the word "buzz" is stamped correctly as one of those factors leading to bad kanban implementations where basically the term is used as a "permission giver" by hipsters.

Some people simply like to use buzz words. Find out who is actually using "kanban" as a buzzword through some simple questions in the first link. Furthermore I would say you should respond to those questions yourself if you are planning to introduce kanban.
