Hello, Google+ universe! A lot of people have added me to their circles in recent days. If I haven't circled you back, it's not because I don't appreciate it or that I don't care to communicate with you. Like most people, I haven't fully sussed out exactly how to make this work best, but there's a method to my madness.
If you and I don't actually know each other, chances are you've encirclated (encirclized? what exactly is the verb here?) me because of my role in the world of game design, writing, or general geekery. I make all of my posts on those sorts of topics public. By not creating a circle for that sort of thing, A. I have to maintain fewer circles, thus lessening the chance that you'll fall through the cracks and miss those posts, and B. if you want to share things I post, you won't get that annoying reminder every time telling you I only shared it with some people and it might be private.
I'm only maintaining circles for family, close friends, and colleagues. That's where I send my posts about family stuff, my kids activities, politics, and so on--things only people in those circles would care about anyway.
We're all new to this, and maybe I'm doing it all wrong. I suspect we'll all adjust the way we use Google+ as we get more used to how it works (and how it works for us individually). For now, though, I appreciate that you've chosen to follow what I have to say. Don't think a lack of encirclization means otherwise!
