I think some long time Google users have actually missed the point of the new changes. Google wants us to share but with very specific targeting. And using those blue buttons.
If someone asks to join one of your circles and then complains that you are posting to them?
We must ask the question. Have they suffered from some kind of mental retardation in some way or are they just just trolls? Or have they not RTFM.
Out of over 500 followers on Google I have had 2 people that have asked to not be posted. Not a bad ratio I would suggest.
Some people will moan just for the sake of it. Hubpages is not in my opinion considered spammy. I could be wrong but not from what I see.
