I found Google+ great for collaborating with the maker community. The strength is use cases that involve discovery of pictures (&diagrams) + discussion of ideas/things, as the communities feature works well for this. Adafruit is making great use of hangouts as well. However, I find that Twitter & Facebook work much better than G+ as news feeds.
