As a teacher with 35 years under his belt, I posit that men and women are different. In my - admittedly limited and anecdotal, and restricted to younger that 18yrs - experience there is a different communication mindset with girls compared to boys (women compared to men?) . I constantly see girls in groups of 8 or so with often one queen bee, and lots of conversation, whereas boys are generally in smaller groups and are quite happy to insult each other, throw a punch and grunt. Facebook emulates what I see in the yard with girls, Wiki-whatever emulates what I see in the yard with boys. Shoot me down if you feel the need to do so.
