I guess, HootSuite seems like a proper Role Model:
An interesting fact is, that Google+ is mentioned to be part of only an "Enterprise" version of it.
That and what's written about Google+ Pages sounds like Google plans to support external partners or APIs but probably just on an
Enterprise level like those users who pay and integrate GMail and other Google services already for their Business.
HootSuite itself also has APIs, so it doesn't necessarily mean it competes with some of Agorava's modules and features. It may also be connected.
