Social networking insights on a surf weekend

This weekend I went surfing down in Devon and found out about 'rah' Facebook. Some surfer (wearing a signet ring and a supercilious manner) told me he "couldn't believe" I didn't know about A Small World. Apparently it's an invite-only social network for Eurotrash, celeb wannabes and hooray Henrys everywhere. "Really useful" I was told, for tips on where to hang out in new cities if you're rich and famous. This digital version of an old boys network, with its 150,000-strong membership is a luxury advertiser's wet dream.
I'm still waiting for my invite.
