Circles, as youre probably aware, is the big privacy-enhancing feature. A presentation titled The Real-Life Social Network by user-experience designer Paul Adams almost exactly a year ago went viral in the tech community; it looks likely this was the genesis, or at least a crystallization, of the Circles concept.
But Adams defected to Facebook a few months later, which lead to speculation that it was the end of whatever plans Google may have had for the concept. But little did the world know at the time that Plus was a company-wide, bet-the-farm initiative involving 30 product teams and hundreds of engineers, and that the departure of one made no difference.
Meanwhile, Facebook introduced a friend-lists feature but it was DOA. When youre staring at a giant list of several hundred friends Facebook doesnt do a good job of discouraging indiscriminate friending categorizing them all is intimidating to say the least. My guess is that Facebook was merely playing the privacy communication game.
Why are circles effective?
I did an informal poll to see if people are taking advantage of Circles to organize their friend groups. Admittedly, I was looking at a tech-savvy, privacy-conscious group of users, but the response was overwhelming, and it was enough to convince me that Circles will be a success. Theres a lot of excitement among the early user community as they collectively figure out the technology as well as the norms and best practices for Circles. For example, this tip on how to copy a circle has been shared over 400 times as I write this.
One obvious explanation is that Circles captures real-life boundaries, and this is what users have been waiting for all along. Thats no doubt true, but I think theres more to it than that. Multiple people have pointed out how the exemplary user interface for creating circles encouraged them to explore the feature. It is gratifying to see that Google has finally learned the importance of interface and interaction design in getting social right.
There are several other UI features that contribute to the success of Circles. When friending someone, youre forced to pick one or more circles, instead of being allowed to drop them into a generic bucket and categorize them later. But in spite of this, the UI is so good that I find it no harder than friending on Facebook.
In addition, you have to pick circles to share each post with (but again the interface makes it really easy). Finally, each post has a little snippet that shows who can see it, which has the effect of constantly reminding you to mind the information flow. In short, it is nearly impossible to ignore the Circles paradigm.
