Atticus Rex writes "The fact that our social networking services are so centralized is a big part of why they fall so easily to government surveillance. It only takes a handful of amoral Zuckerbergs to hand over hundreds of millions of people's data to PRISM. That's why this Slate article makes the case for a mass migration to decentralized, free software social networks, which are much more robust to spying and interference. On top of that, these systems respect your freedom as a software user (or developer), and they're less likely to pepper you with obnoxious advertisements."
On a related note, identi.ca
is ditching their Twitter clone platform for pump.io
which promises an experience closer to the Facebook news feed. Unfortunately, adoption seems slow since Facebook, Google, et al have an interest in preventing interoperability and it can be lonely on the distributed social network.
