I meant in practice. You could, but do you? Does anyone? What happens when your computer shuts down for the night?

Email is centralized in that individuals usually register with a provider, rather than use their own machines. I think social networking can adopt a similar model so all we really need is an easy way to pick up our social data and go to a new provider. I mean who I consider to be my friends is my data, so why not have a systematic definition of it that can be carried with me to every site, instead of recreating those connections using whatever interface is on each of the social sites I use.

It's still decentralized. Not one company has access to all e-mail, as with Facebook.

Of course it is, I'm not saying you're wrong. Although usually one company has access to all your email. As far as the user is concerned it's still centralized. That is, our data is still stored in a centralized place. The protocols for these open social networks however call for decentralizing all the way to the user level, and that's not how email is (though it could be).

I think you've picked a poor analogy with regards to email. It's actually the perfect analogy for a distributed social network. With email you can host your own, use your companies, use a free provider (hotmail, gmail, etc) or use your ISP.

It's not possible for one company/person to get across all your email because you can have it somewhere else. It's not possible to store Facebook info outside of facebook.

I imageine a distributed social network being a woven fabric where some people host their own, some use their companies (think bands using their labels server), a lot of people use free ad-based services (think hotmail or yahoo diaspora). However, no one company would ever have all your data, and couldn't hold it to ransom, assuming some type of export facility is built into the design. For I can import all my emails into a different server, but I can't export all my facebook data. Once switching costs are reduced to negligible, then competition for features, usability and, yes, privacy, wins out. Same way as plenty of people decamped hotmail and yahoo for a shiny new gmail account when they had better featurs and an import facility.

Sorry, what was my analogy? I'm saying distributed social networking should work like email and you just described it. However what I don't think it should be is decentrAlizing down to the user level. Another problem with standardizing the system is that new or special features will not be cross compatible, however that's another issue for another thread.
