It's a shame that maintaining the web is so hard that only a few websites are "good citizens". I wish the web was a -bit- way more like git. It should be easier to crawl the web and serve it.
Say, you browse and get things cached and shared, but only your "local bookmarks" persist. I guess it's like pinning in IPFS.
It is not possible right now to make hosting democratized/distributed/robust because there's no way for people to donate their own resources in a seamless way to keeping things published. In an ideal world, the internet archive seamlessly drops in to serve any content that goes down in a fashion transparent to the user.
If you make it possible for people to donate bandwidth you might just discover no one wants to.
The wanting to is in my mind harder. How do you convince people that having the network is valuable enough? It's easy to compare it with the web backed by few feuds that offer for the most part really good performance, availability and somewhat good discovery.
It's not hard actually. There is a lack of will and forethought on the part of most maintainers. I suspect that monetization also plays a role.
Keeps the spotlight on carefully protected communities like this one.
