Having seen enough story in the vein of "if only I still have my bitcoin wallet from 2014" and "our storage server failed and when we tried to restore from backup we found out our last working backup was from two years ago," I have to say I have a rather dim view of how competent people actually are when it comes to keeping backups working.

I am not saying cryptography isn't useful for safeguarding your data, I just think for perhaps 90% of the users out here the risk of being locked out of your data permanently is more realistic than your data being accessed by a bad actor.

From reading the website, I was under the impression this is a techie oriented project still looking for technically inclined early adopters instead of something you can readily tell grandma to hop on. I sincerely doubt the average friend and family member who needs other's help to set up a personal website knows what the protocol does or why should he or she use it instead of Instagram or Facebook, or Signal, if the point is just to keep in touch with people you already know.
