Not necessarily. If celebration has a function (e.g. encouraging a certain type of behavior from those capable but currently unwilling) then celebration should most certainly not be tossed out.
Celebrity culture has troublesome elements, certainly... but successful, influential and/or proactive people DO tend to have more interesting/useful things to say. "Don't get into stupid small talk / lifestyle gushing" seems great, but celebrating thinkers is not a bad thing.
