QR codes for canonical addressing could solve the publishing problem, with customization of how the QR code appears being a feature for advertising and marketing. Once the canonical address has been accessed once, it could be pet named by the accessing user.

Good answer. But I’m wondering how well this works when a QR code resolves to a meaningless string of digits?

I suppose most people don’t check URL’s anyway, and for some URL’s the domain name is fairly meaningless. Still, it seems like something is lost, at least for techies, when you can’t see and recognize usernames and domain names?

Consider how programming languages work. Who wants meaningless numbers in their import statements or package.json file? Package names seem decentralized enough? Not sure it’s worth throwing out to achieve True Decentralization.
