For myself that convinced me immediately to kill my own "real name" account. I replaced it a few days later with a pseudonymous one (before pseudonymity was explicitly OK'd by Google many, many months later).

I agree fully that that one misstep put Google's home-turf advantage with the technorati early adoptors and poisoned the well. I don't think the company or platform ever recovered.

In conjunction with other moves by the company (culminated with forced YouTube-G+ integration which I've termed the Anschluss) cost me all faith and trust in the company. To the extent I can minimize my exposure to and use of it, I do.
