The Ultimate G+ Collection: A Treasure Trove of Google Plus Tips, Guides, & Resources
Here is an extensive database of Google+ resources that I put together for both newbies & power users. I'm sure there is something new to discover for everyone :)
The collection is large, so I decided to break it up into 11 sections and have it hosted on sociologyplus.com, a new website I contribute to about the sociology and culture of Google+, as well as other Google+ related events and information.
