I was reading an article about why a particular website was moving away from the Facebook Platform (http://news.ycombinator.com/item?id=2549468) which got me thinking about the Diaspora guys (https://joindiaspora.com/).
The two biggest issues for me about Facebook and what keeps me from using them as ubiquitously as Google is:-
(a) I have no control over what happens when I upload stuff (pictures, status updates, notes, etc) to Facebook.
(b) The lack of ability to separate my family, friends and work social circles.
These 2 issues of mine with Facebook is apparently addressed by Diaspora which i signed up for an invite as soon as they announced themselves in April 2010. Fast forward a year later, i've yet to hear any updates from them.
So, has anyone heard anything?
