I have a less common take on social networking. I'm not interested in becoming famous for my Google+ posts, nor do I care to spread my "influence" far and wide.
Reasons I won't be circling you back:
-You're using an obviously fictitious name. While Google+ no longer requires real names, I prefer them. I find there's less trolling and drama when people don't get to hide behind a fake name.
-You're posting NSFW content publicly. I am often in places where others can see my screen, including work, and I don't want to have explain genitals to coworkers, bosses, or angry parents. Part of my job involves social media.
-You have no posts visible to me or no posts and no pictures. How am I to get a sense of who you are and what you're about if you don't have any posts?
-You've got hundreds or thousands of people circled. I value quality over quantity. I sincerely doubt you have the time to keep up with posts from hundreds/thousands of people, which means it's also unlikely that you will have the time to get to know me in any significant way. There's nothing wrong with circling hundreds of people, that's just not how I network.
-You haven't posted anything I can see in several weeks/months.
