Here is a #gplus Circle of the Top 50 Members of Inbound.org This Circle is manually created from http://inbound.org/top-members
as of 20th February 2012. Ideally I would prefer to see, in addition to this, at least an all Members circle but that's not possible based on the available public information.
On the whole I've been pretty stoked about the content shared by the Community which supplements, albeit overlaps a little, with Twitter, although I do confess I was hopeful of more debate in the threads.
Personally I find that the composition of the share pie http://mmkt.in/inboundsharepie
still leans too much towards pure SEO (at 29%) although that's understandable based on the seed list.
However it is somewhat short on those areas that so much pro SEO opinion has deemed important in 2012+ I'm referring to the Categories of Video, Local, Mobile.
I think it would also be welcome for Members to exert their attraction charms to bring other marketing professionals onboard in those categories where the numbers are relatively low.
I'm hopeful the Community will evolve onwards & upwards as will the functions and integrations of the site.
Thanks to all of you.
