Also, here is a little background on G+ to help you
*On Google+, you can post to Public, which means the whole world can see what you wrote.
*You can also post to a particular person or circle you created (just family, only people you work with, etc.)
So, you're in complete control of who sees what of yours on G+. If you don't want strangers to see your posts, you don't add them to your circles, even if they have added you to theirs. If someone adds you to a circle but you aren't interested in seeing their content, you can block them (the old-fashioned way) or "Ignore" them (You won't see their content any more, and they won't know that.)
Recently, on Google Plus, I commented that I don't just circle anyone who circles me. In fact, I'll put it right out here and admit that I am shallow when deciding whether or not to share my content with someone. Just because someone has added me to one of his/her circles does not mean I have to reciprocate. I'm not just going to flood my stream (like a Facebook wall) with random crap from strangers. And because I don't have all the time in the world, I often cut-to-the-chase and simply click Ignore, rather than clicking through to the person's profile to see if I wanted to circle them back. On what do I base this trigger reaction? Profile pictures.
For example, here are a number of Plus profile photos of people who circled me and inspired me to click "Ignore" almost immediately, without even visiting their profiles:
Now, let me add that I don't fault people for appearing unstable, but I do fault people who don't have the self-awareness to know that their photo
This guy looks normal, no? That's what I thought, until I saw his name:
"---- Is Single"
Who does that?!
(besides that guy, I mean, and yes; I took out the letters of his name)
Then there was this guy...
Again, I'm not judging the appearance; I'm judging the self-awareness thing. (That suit is hideous!)
Camera angle is everything in a profile photo.
It can mean the difference between friendly and fiendish....
"Hi" and "High"
And then there's this guy...
So, yes; I'm shallow, if shallow means happily-married, sober, and discerning.
If you are the owner of one of these profile photos, feel free to message me for a free consultation on how you, too, can give the appearance of being normal in your profile pic.
While writing this post, I made a point of actually looking at the profiles of these plussers, and I stand by my decision not to circle them back, and not because any of them actually are serial killer; we just don't have a lot in common.
Update: Today, I was added to this guy's circles (in case you're curious, the circle is called People with a Sense of Humor, or something like that).
Masterfully, Seth's profile photo demonstrates "creepy, but in a silly way." I'm happy to report that I checked out his profile, he seems normal, and I have added him to my "Seems Normal" circle.
