I think you're over analyzing. G+ is out for barely two weeks now. It has not even been released to the general public. Any internal strategy Google itself has is merely of speculative nature until it gets proven or not.
Any great strategy is merely speculation also is figuring and/or anticipating other peoples moves. A great strategist needs to have a great gut feeling and be lucky. When Napoleon was presented with a new officer and after his merits have been presented to him, he supposedly asked "Very well, but is he lucky?".
That is why bean counters never get to do anything great. And that is why people love good speculators. And all the guys I mentioned are incredible speculators.
Not everything can be quantified and analyzed. And regarding curation - the community has decided that this specific piece of speculation is interesting and insightful. I hope I don't need to remind you that this particular mob is not you average Joe Sixpack mob?
