Well it may be like that but it is Google's first attempt in Social Media. You are enjoying the Social Media scene under the name of Google brand. The version that is being used is just an attempt not the full version so you can expect some new features in the future.
I haven't figured out the "social" part yet. It seems more geared to reaching the people you already know.
I think it's because you are more into other social networks. I also use google+ and as of now, I can't put my interest in what it has and what it can offer. I'm much into facebook that is a user friendly one. But I think google+ will give a good fight in socializing if google will start in opening their social network to all possible users.
I really like how its setup, especially the circle visuals and what not. My biggest pet peeve with Google + is that there's no business page! It won't compete on a personal social media level with FB, Facebook has too many users with years and years of use. Google + would be amazing for business networking though, hopefully they implement that soon.
