UPDATE: Just had a long talk with @justinfreid, about this.
I’m rushing this post out, but I’m really impressed by what I see. What I’m talking about is google+. Google’s answer to social networking, and I think that google not only hit it out of the park, but hit it out of the stratosphere. Being so nascent, hidden features will come, but this is what I see:
First, how did I get an invite. If google planned this, then it was genius. They gave invites to the celebrities. This is standard operating procedure. Then they opened up the floodgates, but allowing invites. Not just 10 invites, but an unlimited number (I must have invited 30+ people without it blinking). This allowed the people who wanted in to be in, and invite those who they thought were useful to join. Immediately after, Lifehacker.com posts invites, and everyone joined. In 20 minutes, I had four friends, already posting, +1″ing,” adding photos, and commenting. Within the hour, I was “hanging out.”
