You'd be surprised at how relatively few old friends I have on FB, Andy! There are not many from "way back" at all. There are a handful of WABbers among them too (I haven't yet got the average 60,000 "friends" yet as I am quite a newbie there as well lol ;))
(Btw, I am actually a few miles along the coast in Hastings, but the nearest FB network to here is Brighton :)) D.
