Deleting everything on Facebook is NOT likely a good way to increase engagement on a separate platform. More likely, people will just forget about you! The problem is, with the Dunbar limit, these tools serve part of peoples memory. There almost certainly MUST BE A TRANSITION to the new peer based tools.

Why doesn't Ven Portman / Ev Bogue mention PGP? I don't see his public key anywhere, why talk about emailing people what you are working on openly if you want to "evolve beyond reach"? Hard to take seriously.
