I can't help but feel that the original list skews a little "nerdy" and aren't really a draw for most people. Some of the arguments are just specious and/or dubious. Privacy & trust? Facebook's privacy controls are actually more fine grained than Google+'s and Google's track record with respect to privacy is just as mottled as Facebook's and includes some higher profile incidents as well. Did we all forget about the Buzz release? Google ecosystem and a "blended experience"? There is absolutely no evidence that there is demand for that and my gut feeling is that there isn't.

The rest of the arguments are just as spurious and the article is, in my opinion, representative of the tech world's flawed and narrow take on Google+. It seems like most commentators have let their analyses be skewed by either an irrational dislike of Facebook or a love of new technology. Neither of these will drive people away from Facebook or towards Google+. Furthermore, a lot of these arguments seem, sometimes implicitly, predicated on the idea that Facebook is just going to stand by and let themselves be steam-rolled by Google. Google is the underdog here, they have a lot of failures under their belt in this area and at the end of the day, despite the novelty involved in binning friends into circles, Google+ is just a Facebook clone.
