Don’t understand Google Plus

So I recently tried to go on to Google+ to try and network and market my books on social media.  That thing looks like a maze!  Am I getting to old for new social media or something?  I was able to grasp twitter more or less.  Google+ just made my head spin when I looked at it.

Maybe I’ll have to check it out when it’s not one in the morning.  Maybe that might have something to do with it as well.
