He's trying to say that by stating that a brand new service that is, by most measures, doing fairly well is "failing miserably", you've lost your sense of perspective.
Fair enough. The submission title does say google+ though. Additionally, I think strong statements like 'failing miserably' require strong evidence. This seemed more like (weak) anecdotal evidence and opinion to me.
Oops, you're right. Somehow skimmed over that on my phone. Apologies. Still I think the actual blog title is a little bit less sensationalist than the submission.
