[Freedombox-discuss] "What's a Distributed Social Network?" -- the comic

[Jake Emerson]

The "distributed" term probably caught hold with SETI at Home program that 
loads of us ran as a screen saver back in the day (or still do?). That 
program had a goal of breaking the task of searching through cosmic 
radio signal data in to bite size pieces. Idle machines masticated the 
small pieces, and sent their results back to a central DB. One 
goal/program split across many computers is distributed.

With peer-to-peer networks things get even trickier. We've seen loads of 
folks talking about distributed computing or networking in that context. 
However, a P2P network (one with no central node, anyway) has a 
decentralized network topology that *enables* distributed computation. 
The network itself is decentralized, but it can help make distributed 
stuff happen. With plug servers we aren't trying to compute any one 
thing, we're just setting up the (mesh/ad hoc/variegated) network.

"Decentralized network" probably evokes an accurate picture in people's 
minds, and that could help tell the story. Just a thought to chew on 
while the project is still young.

Cheers,
Jake
