Anyone else playing around with this? When I read the blurb it just looked like another social media googfail, but actually using it I can see some potential. The core parts are it's 'circles' - pots you put contacts in, such as a 'friends' circle, a 'family' circle, a 'company a' circle, etc. which are actually quite user friendly, and superior to FB when it comes to securing content. There are also 'sparks' which are essentially feeds of things you're interested in, these don't come across as all the great to be honest. Maybe after a bit more playing. There are also going to be 'huddles', not seen any functionality for that yet though.
