I haven't been as active here as I was several years ago, but from what I've seen it still seems much "edgier" and less complacently mainstream, whether for better or worse, than the others I've encountered.
Australian's will know what I am on about, we don't care about celebrity and fame, we just take people for who they are.
Online there is a strong tendency for some to criticise those who stand out. Tall poppy syndrome seems to be a big thing for certain places in the world. In Australia we generally cheer people on if they stand out and do much better than ourselves. We are happy for others to do well for themselves because it doesn't mean they are any better than us, the mateship between us is so we are not jealous (I am writing in generalisation because of course there are people are jealous but it's just not so common). But in other parts of the world it is more of a "Keep up with the jones" type attitude when you observe those doing better than yourself. My relatives in Germany explain how it is so common to get something new just because your neighbour did. It seems a natural pattern that those who want to keep up but cannot keep up then go ahead and cut others down calling them arrogant, show offs, boasters, in need to become more humble etc.
