Facebook is indeed pissing many people off, including myself and I find the circles system and the general looks of G+ much more appealing. But the main reason why G+ is not pissing anyone off is that there's absolutely no one using it !
Yes, I know, millions of people have a G+ profile, but that's just because they clicked on a Yes button one day without reading the text above it and voilà, their Gmail or Picasa account was "upgraded" to a G+ account.
If G+ ever turns out to be succesfull, I'm afraid there will be as much scam and ads than on Facebook... and the fact that G+ is linked to many other Google services many people use is even more vicious regarding privacy...
