at work we have an intranet site on which we are all required to create a profile containing professional and (some) personal information. you also have to include a photo. you can add colleagues to your ''friends'' list too. lots of workplaces have these things. i think they're a bit shit but i go along with it so as not to attract attention.
one of my colleagues has no photo, no professional information and, under ''interests'' has listed only ''hunting''.
