I think the author makes a similar point (about third party hosting services needing safe harbor) when he points out that Amazon EC2 is like the landlord, who of course can't be held responsible for underage drinking at the club. I agree that appliance-esque simplicity is what is needed to allow/encourage "civilians" to host their own content, and I hazard to guess that the author would too. And what is stopping us from creating that?

I remember in my freshman year of college when students discovered the library sharing feature in iTunes. Word spread pretty quickly, and soon most folks were using their laptops to do what the Zune tried to popularize: sampling the music of peers for free over the network in order to connect over musical taste and find new bands. I think what the author points out is that other programs have similar features (such as iPhoto being able to share a folder of images to the network), but they are limited to local networks and can't be reached from everywhere. Why not institute a system that allows that same "share my photos" check box to make them available on the web? Then I, and many of my friends who have faced the same problem, won't have to create a facebook account just to be able to see a friend's wedding pictures...
