@saab,
Yes....a lot of it is putting people down type of gossip...but sometimes it's just interested recounting of what adventures people have been up to gossip.
Is it still gossip if it's nice?
It's certainly very bonding in a funny sort of way if it is critical.
It would be fascinating if, after enough time had passed for us all to die, a social psychologist/anthropologist could access all the PMs from a site like this, and analyse the gossip.
By nature, except for letters and those damned gossip magazines, it is an ephemeral beast and, I would have thought, hard to study for that reason.
I am sure it has indeed been studied before,....do you recall what the 1975 book said, Saab?
