The program “Nexus” was built as a Facebook application (I don’t know if any of you guys have this, there’s a similar application called “Friend Wheel”) which calculates friend similarities, categorizes them by groups, and so on by a series of interactive lines.  When you select one of these lines, it will highlight and show who knows who.  I thought this was similar to the website we saw on class on Wednesday which showed the executive board members of different companies and who they were also affiliated with.
