Interesting website found the other day. Idea is that brings in everyone you have contact with via email, twitter, facebook and linkedin etc.
So can see all the different contact for example if I bring dos_box details up then it shows all my emails to dos_box. only thing I would like to see them add is some CRM stuff so can do things like next actions etc.
Gist - Organize, Connect, and Communicate with contacts from your entire professional network.
