The work environment is rapidly changing... as well as what's appropriate in public forums. Several months ago my department was briefed that discussing sports (like scores from the night before) had a negative impact on the workforce because it potentially excluded females from the conversation... it made them feel excluded. (Which actually is sexist belief of itself, but whatever).
Ironically, we rarely discussed sports.. just brief conversations. However, in the corporate melting pot of bringing together all genders, races, ideas, interests, hobbies, experiences, and backgrounds(which is great)... but there seems to be a target on the percieved old school interests.
