The inevitable direction for communications media seems to me to be toward an entirely server-less model. It is cybernetic in character as it assumes that the individual(s) and the machine(s) which mediate communication are unified as nodes upon the electro-social mesh.
This mesh has no center and no circumference.
To be more specific and less poetic, Bittorrent is an example of a P2P (peer-to-peer) technology which can be used to create social networks from individuals and their own privately-owned devices.
I2P is an emerging software technology that adds a secure and anonymous P2P mesh network layer atop what is typically referred to as "the Internet".
Beyond this, the next great step in electronic communications technology will be to ditch the ISPs and figure out how our devices can connect each other to each other, rather than through centrally-owned corporate conduits. A lot of work has already been done with this, and we (as regular people) have ready access to all the hardware we would need to create such a network.
For example, young adults in the Red Hook community of Brooklyn have created their own wireless mesh network. In their own words,
> Red Hook Wifi is a community-led project that aims to create economic opportunities, close the digital divide and improve the quality of the life of the Red Hook community. It bridges residents, organizations, and businesses together while serving as a lifeline to create a neighborhood digital community. This effort will be led by the “Digital Stewards”, a group of young adults between the ages of 19-24 who will help maintain, promote, and install this network.
Their community portal can be found here.
So while the traditional character of "cyberneticism" has been that of individuals merging with machines in order to access ever more abstract layers of power, it seems that this should be updated to the notion of communities of individuals organizing in order to utilize technology to improve their immediate, shared interests.
The social network of the future will necessarily be built by you.
