So you’ve gotten an invitation to Google+ and you’re not sure what to do next. Is it the new Facebook? The new Twitter? The new LinkedIn? You can find people using it like all of these, as well as people who seem to be using it in a way all their own. But where to start? Here are a few primers produced by early adopters, with tips you may find useful.

Chris Brogan has some suggestions and some how-to videos to offer. He recommends starting with security settings, to make sure that you’re sharing in the way you intend.

The Huffington Post has tips about circles, who to follow, and more. They’ve also got suggestions about “sparks” and “hangouts.”

So go forth, +1 to your heart’s content, and build your Google+ world in a way that makes sense to you. It’s an odyssey of discovery.
