I have over 600 people in my Hacker News Circle, i see on my 1080 screen right now 1(!) Post in the stream. On HN i see 30 Posts with a transparent voting system, that works really well. Why should i waste my time on G+? Google+ Pages is something different, maybe i go there on purpose, but how can i explore something in the stream?
