I’ve been looking at what the IndieWeb guys have been doing, and so far I’m pretty impressed. It’s still perhaps a little too geek-centric for the normal people to grok, but that’s a matter of education and UX more than technology. Still, the personal-site-as-homepage harkens back to the early days of the web, which gives me a nice warm feeling.
Whatever happened to Diaspora? I’ll have to look that up again, although if I recall correctly the underpinning idea wasn’t too far off what BuddyPress has become.
