Both. Can't choose.

The Pear Stack and Nostr but have enormous potential and for slightly different reasons. I really kinda think that the more time goes on, the pear stack will be a dominant way of delivering files, resources, and building your own networks between devices, while nostr will serve largely as a global identity, social graph, and payment directory on top of it.

In other words, I think both are trying to be the entire stack, and I think each will settle into their "optimal place" in a combined stack... at least it intuitively seems taht way to me right now.
