Community. Peers. Group. Network. Friends and followers and contacts. There’s almost as many terms for ‘them people wot you know’ in social media as there are social networks. But you know and I know that lots of the people you ‘know’ are, in fact, complete and utter strangers. Maybe you met them at a conference for three-and-a-half seconds. Maybe you liked their avatar. Maybe they’re a friend of a friend of someone you met at a conference who had a nice avatar.
