Agreed. I have used it every day since the private Beta in June 2011. For me, I like it mainly due to my obsession with photography and geeky subjects of which there is a constant abundance of information. As the poster above stated, "If you're not following anyone, no wonder it seems barren." To be honest, compared to the useless crap and continuous flow of drivel that I used to find on Facebook on a daily basis, Google+ has been a life saver for people wanting to find a place where they can easily communicate with like minded people via Hangouts or just messaging. The noise filters are also great. Also, the ability to chat to the Google devs behind the system directly to get things fixed is a great sign that the development is ongoing and something important to them. There are also constant improvements to the site and how people use it, that I never saw on Facebook.
Yes, I know that FB would have GUI and back end updates, but they were always annoying at best, and fairly useless in usability. Remember, Google+ is still less than a year old.
Take a look at what Facebook was like when it was a year old.
