I get sick of people adding me as a “friend” on things like Blog Catalog when they cley obviously haven't even bothered to read any of my blogs. Is there a polite way of telling such people to piss off?

I really wish there was a social networking site that would allow one to distinguish between close family, extended family, close friends, friends, acquaintances, work colleagues, business contacts, and online contacts, and to show them different stuff. There is stuff I wouldn't mind sharing with a friend of a friend, but not with an acquaintance of an acquaintance, or a “friend” of a “friend” (neither of whom I know at all, and neither of whom wants to know me (or they would have read my blog).

PS What's happened to Wired Gecko? Who is Go Daddy?

PPS Happy holidays, as the Americans say.
