I think I am bit late to discuss “Social Objects”. I was reading a blog where the author was comparing Linkedin with Facebook. Both are public facing web sites where we network, one is professional and the other is personal.
One question I have in my mind is “Why do we network”? When I realized, I found that we network to share. This sharing is of personal belongings like Photographs, Status, Feelings and Chat when it comes to social networking site and the same translates to Experiences, Knowledge, Appreciation when it comes to Linkedin.
So people actually network to “share” and these sharable objects are nothing but “Social Objects”. So any public facing websites which allow networking should keep in mind the social objects through which they are trying to bond the users.
