But I see now that I need the Google+. It has things the others don’t. Circles, for one. I can divvy up who I share what with in the same platform/account. There are tonnes of great communities to join with events like the new Google Educators Group (GEG) for central Bangkok (and more being made as I type!).
And, you can see how much traffic you are producing which is not an obvious functionality in Twitter.
Final word.. If you are in the game you should add this to your connectivist corral.
