I think Fb's current problem is that, while they were never perfect, around a year or so ago, I could get access to all the information on there I wanted, while easily filtering people/posts out with the "ignore" function.
It all seems to have become convoluted, and the ticker just kind of pisses me off at a philosophical level. If I hid these people, I don't want to see their posts, let alone see the posts they make on people who I am not connected to's walls.
I would like the ignore functionality placed on G+. While I may add someone to a circle, if their posts provide no value I may want to just ignore them rather than remove them completely. And for definition, for a post to have value to me it has to be something that can be discussed, something that is humorous, or a link I find interesting. There is no 100% success rate, but Fb became bogged down with lots of people bitching about their first world problems who I see are now beginning to migrate over to G+... mostly they're folks I knew in high school actually.
