I expect there will be many ways. A simple one is for people to publish an address where they publish data which others choose to follow. If I’m following you, my app would poll that address to see if it is changed. And if I follow several people it can merge that into a single UI.
You can do this with different Autonomi data types already.
I’ve just added support for public Scratchpads to the dweb REST API for Autonomi and was wondering about making a simple demo using that. Maybe this is the motivation!
Lists of DwebNames could be ‘followed’ in the same way and merged into your own list along with others, and an app could search all these when you start typing an address, offering you a choice of names created by yourself and others.
The topic is about discovery, but once we have people to follow, we can share things as with all social media. Discovery doesn’t need to be via search, and none of these things need to work the same way as the current web. That’s why I expect different approaches.
