How are you assuming the split would work? The networks would be isolated from each other? That's not how I imagined it at all. When Bell was split up, you could still call people on other networks. I'm interested in different ways of doing it, but in almost any scenario I think the networks would all be federated. Like email. You would still have all your distant friends, their messages would just originate from a different server than yours, with different corporate ownership. You could live in Japan and use the Central American product if you wanted. Many would switch around, that would be the point... some competition. If any network got too big it would just split again. Geography would force users under a specific service provider only at the moment of the split. After that it's a market-based free for all again. There would just be n forks of the Facebook source with n corporations in n regions, and shareholders would get 1/n shares of each stock. I think it would be a boon to both social networking and shareholder value.
