Last week I gave Google a small pass for launching Buzz with serious privacy problems and a too-hard-to-find “off” button, saying that at least they were iterating quickly and openly, correcting their mistakes. Today I’m happy to see they continued to do so this weekend, even after I wondered if I spoke too soon. Significant changes to how Buzz works will be rolling out which address most of the problems it has. Would you see this kind of quick and apologetic about-face from an Apple or a Facebook? I don’t think so.
