Apparently, 120+ different people have been working together (or just at the same time) to create the Ultimate Google+ Users Guide. Over at our new sister-site, GooglePlusTalk.net, we did a writeup on the new community created project that aims to make learning Google+ easier. You would think the effort would end up being a "mess", but their hard work has really paid off, and the guide is very useful. It basically is the, "everything you wanted to know about Google+, but were afraid to ask" collection of dynamically growing info. Isn't it amazing what people can accomplish when they work together? Now, if the nations and governments of the world could take lessons from these folks, then we could solve world peace!
Here's some links below for your perusal, and don't forget to check out our cool new sister-site @GooglePlusTalk.net!
