From what it looks like every user is assigned a URL just like a domain. While they use the term app they appear to be webscripts to be used within “your domain” and not really like phone apps.
So it looks like everyone basically has their own personal website or “pod” and domain with features they choose including socialization and file sharing like you mention if you like.
Actually it looks quite interesting in concept. And it’s free too. I need to play with it more...
The important thing is that it has no registry dependencies like the current web. It is a totally independent registry and URL addresses.
And this is all it takes to create a whole new internet... Different URLs.
Well, it is one thing to make a technology that appeals to technologists, and quite another to make one that can be used by the general public. That is what is at issue here - getting John Q Public to quit playing in the facebook sandbox. I am not seeing that in this idea.
