Social networking is great, but there is something fundamentally wrong with the way social networking is implemented today in most popular services. I'll put it in this example: Imagine that there is no SMTP, and consequently, it is globally assumed and accepted that you can only send email to addresses on the same domain. The result would be the emergence of a single email service, let's call it emailbook.com, which we all have to subscribe to, if we really want to communicate with the world.
This is what's happening with social networking today. You HAVE to use the same service your fiends/colleagues are using to talk to them.
I would like to be able to put up my own social site, invite my friends who trust me, share amongst us, but still be able to share with the world at large.
What are the chances of this scenario happening in the future? What does it take?
