OK, Do I have Google +? Or not? →[More:]I think the answer is probably "if you have to ask, you don't." But I've got the black bar, and when I search I have a little icon that allows me to recommend a page. And I was able to make a profile (I was also invited to a Google group today, so maybe that's why?). But my recommended pages seem to map somehow to my profile.
Is this it? Is there more stuff? I tried reading about it, but it is making me more confused. Hope me!
