I think an easier way to do this without getting all the sh*t from everyone else would have been to say:
"Hey, who here uses G+? I'm starting a TPF G+ circle and I want to add people to it!"
Then quietly select who you actually *want* in your circle... and then when you're satisfied share that circle for other's to use.
Wouldn't that be accomplishing the same thing?
I think people are freaking out because they don't understand how the G+ circles work... but I think I get what you're trying to do... and if that's the case, then stating it the above way probably would've saved you a lot of grief.
Cause really, that's all your doing... is creating a circle of people you want to communicate with via G+... and then just passing that list off to others who want to tweak it. It's not like the changes that others make to their version of the circle affect yours at all... so... yeah.
I get what you're doing (I think)... there just probably was a less "controversial" way of doing it, haha.
