Can anyone suggest what might be the alternatives to OG within other CMSs and frameworks?
I only know of buddypress and if I understand that right it's more an alternative to Commons than it is to OG - ie it's a monolithic system, not a granular one that would encourage more customised development.
CONTEXT: I'm doing scoping design for a social site, focused around project pages a little like Kickstarter, each with their own posts, members, etc etc - feels like the purpose for which OG was born, and being drupal native I'm finding myself modelling everything around OG principals.
But at this point I'm to be CMS agnostic, so I need to be able to adequately consider the alternatives before writing a spec for the actual build. So i'd be glad of any insights as to what the alternatives are.
