Beg your pardon daddyo! Peer to peer? I'm writing a reply to someone who could be anywhere in the world, that can be viewed by same. I don't see anything remotely SNA related (I've worked with the real thing - it's more stable).
At a whim I can use another platform, any platform that will allow me to login and participate, to communicate with a vast number of people. Yes, there are the big ones: the FBs and Twitters of the world. However they come and go. I also use mailing lists and was a fan of USENET some time ago.
The internet *is* hugely democratised for the likes of you and I. Perhaps not for people in many countries and that is a shame and we must continue to try and develop and deliver technologies and methodologies that might enable those who aspire to the luxury of reasonably unfettered communication (that we enjoy) to be able to join us.
I clothe myself in far more tin foil than you will ever see in your life but I am under no illusion that I am being fettered in any way. Spied upon? possibly, but only in an uncaring data gathering because terrists or marketing way.
The internet is working the way it is precisely because of the way it is designed and who it was designed for: humans.
