Re: Might be a nice idea, but it'll stay theoretical
Unless there's a way to force Facebook to use this construct, I don't see any change any time soon.
It is a first step.
Obviously the only answer to the problems with Facebook, Twitter, etc are for regulators to enforce competition with open interoperation. Then people can have their "conservative facebook" or their "activist twitter" and still follow their favourite pop stars and Auntie Betty as well. But regulators won't force that until the tools are in place to make it work.
This sounds like one of those building blocks. If it is successful then we can start asking regulators to use competition laws to force the massive players to use it.
