This is a bit of a open secret. I think many in tech think Google+ is a ghost town, and so the joke goes, the only people that use it are Google employees. However, when I was looking around for 3D printer communities, I was surprised that there was a vibrant one on G+. While one data point is not evidence, it is an example that runs counter to the current prevailing tech wisdom that nothing happens on G+. I think while G+ may not replace FB, the interface is great, and we may find social networks have other uses for groups besides what we do on FB.
