Cool. And nice use of "voila".

The drawback to to that, though, is that nothing "pushes" that to the person or puts it in a place where it will persist beyond the normal flow of their stream (what's that prostate medicine that talks about weak stream, I assume spoofs are in progress).

So yeah, only they can see it, but there's nothing that says "Hey, this is intended specifically for you so pay attention!" Assuming they even have you in a circle they read regularly. I've got 50 people in circles at the moment but only 14 in the circle with a stream that I look at regularly.

But then, I don't think I have anybody in my circles that I couldn't email if I wanted to. And if someone isn't wiling to be emailed are they going to be willing to be direct messaged?

Also, trying it, it doesn't appear that the method of adding just names to a share list (as opposed to pre-defined circles) is available by phone app (at least not iOS).

If anybody sees differently, please tell.

Snorting! I can't even spell it right!

On the Android app, when you tap the arrow that brings you to the screen where you can select circles, at the bottom there's a Circles tab and a People tab.

Yup. As described by GD, Android let me send a "for your eyes only post" to Alex

Not on iOS apparently. Just lists my Circles. No people tab.

If you mention their name in the post (+Alex Stroup) it is an additional alert that there is a message for them.

If you don't want your profile to come up when someone Googles you you have to manually remove yourself. Go to settings > google+ settings > profile and privacy > edit visibility on profile > uncheck the box.

I'm confused about who can see who. Is it whoever is in your circles can see everyone else (like before FB made friend lists public) or is it anyone can see everyone?

By default, anyone can see everyone.
There is a setting that allows you to keep strangers from seeing your friends
Once someone is your friend you they can see all your friends
No one can see what circles you have placed them in.
