I think we need to get beyond domains.
In torrenting, objects you publish get ids. The ids are never replicated and belong to that content forever. Torrents are never truly dead, only just sleeping.
A domain is basically a folder on the internet marked “You”. It seems like a great way to organize things until you realize if the folder is ever destroyed all your stuff goes away.
Models like IPFS and SOLID decouple content from display servers, and will be the ultimate solution to this problem. Reclaiming domains is a good intermediate goal, but in the end we’d like to move past domains altogether.
