Thanks! Yes, I find the Diaspora model really interesting, but most people seem to see it as just that – a curiosity. Also, it seems to be more taking on facebook than twitter. What I’d love to see is an open microblogging protocol. The twitter communications model has so much going for it, but with everything going through the same system it’s a massive bottleneck, not to mention drain on resources. Facebook seem to be managing very well having the monopoly on full featured social networking, and they can monetise it through highly targeted advertising. Twitters greatest strength (simplicity) is also it’s biggest problem when it comes to monetisation.
