Google Plus
I've been playing with Google Plus + for about a week now, and I have to say that in my opinion, it takes the best of Twitter, Facebook, and LinkedIn, and brings it together in one well-thought out, brilliantly executed general social network. I've found many of the new concepts on + to be fantastic and look forward to exploring it with my fellow BiggerPockets friends.
Lets use this thread to discuss the features, how best to use it, etc.
Of course, if you're on the site already, please look me up and connect with me.
BTW - If anyone knows of a good way to record a hangout (video conference with up to 10 people), let me know . . . I see the implications for hangouts to be pretty exciting.
