There's no doubt that there has been ample fodder to fuel the misconception that the relationship between OCS and iHub extends beyond Matt being involved in both and some co-marketing.
It doesn't. OCS will succeed on it's own merits, as will iHub. There is no integration at any level beyond marketing. The sum total of my involvement in OCS was maybe an hour doing the hotboards app for the All The Rage page, and I doubt Bob has spent as much time as I have on it.
