Well, I've finally relented, persuaded by Janasalin, I've signed on to Facebook. From a distance it did all look quite superficial, and certainly can be treated that way. Some people seem rather too avidly in pursuit of clocking up a high number of 'friends.' So far I'm trying to stick to 'friending' people I have some form of connection with, ranging from light acquaintance to ardent buddies.
What I'm really enjoying is the simple networking aspect, hearing about others enthusiasms, or what's going on for them, what they're doing in the moment. It also means I can stay connected online with folks I sometimes don't see that often, like my Private Preceptor for instance. I'm not sure whether its meant to be used for anything other than this really,and that is fine by me.
