Social Intranet

Isn't that all social networks are? Just a global intranet, in the sense that one's interests are attached as part of the daily utilitarian grind that is surfing. People claim to not like single source authorship, but thats what they are doing themselves with the internet anyway. Acquiring their own intranet for their own personality, which is their corporate non private identity. In the same way NSFW exists at work and creates firewalls, the social intranet is the corporate identity we try to exude. Linking to each other is like working in the same company, the company of the different angles of view we have of the net.
