Agreed. My problem (and it may just be mine) is that my 100 or so friends on Facebook (mostly IRL friends) are not that active on Facebook groups. They will update their status and post photos but will not share content on groups. I am part of a number of groups around my interests (tech, photography etc) but tends to be me and maybe one or two others that contribute content. Very little discussion occurs. I wonder if Google+ will change that with the ability to add in non friends around an interest (ala twitter) but without broadcast to all.
