Shatner, you've nailed it. Google's +1 is simply not understood and not well known. I checked within my family, and even those who are online for many hours every day had no idea what I was talking about.
It is a publicity problem, and possibly a naming problem, too, as you've pointed out. If any webmaster hopes to get those +1 clicks this early in the game, they need to help promote and educate about Google's new thing - or wait a good while longer.
