I remember the discussion you refer to, and I agree that it's fine--within reason. So, I think, is teasing other members who take themselves too seriously. I think taking one's self too seriously is a bigger contributor to feelings of alienation and animosity than disagreements with other people are.
EDIT: I may be perceived as the most egregious srs-biznizz offender, so I balance it by getting drunk and embarrassing myself in the shouty.
