Yeah, right... I´ll hang around by the station of the east, ok?

Janna you seem to know a lot about Google+ (and a lot of other subjects). Could you tell me how I can have people in my follow circle (or any other than family or friends) without having their posts swamp mine? I love my posts which are about what interests me and values I cherish. I have failed so far to get an answer from Google+
+David E Nebeker You can adjust the volume of the stream for each circle. Click open the nametab for the Follow circle from the left top side of the home (stream) page under your small profile pic and name. Then check the slider top right.
If you want to mute the circle, slide all the way to the left.

You can still visit the circle and see their posts but this way they don't swamp your main stream. Same goes for all circles, there are 4 levels of adjustment.
