Furthermore, Google+ can implement algorithms that affect the prominence of the content based on various quality factors. There's evidence that Facebook has such algorithms in place (1) ...which don't work in most cases that I've seen. Second, the headwinds to gain share in a market with strong network effects outweighs the risk of a flood of content. You're assuming that gaining share is more important than creating quality content. This is not an assumption shared by Vic Gundrota, nor I. Honestly, and I don't mean to be rude, you sound a bit too much like some marketing wonk that someone who actually cares about the product. As many users at whatever the cost to the product quality is just not a winning long-term strategy, and Google always plays long-term.
