Here's a trip down memory lane, looking back at Zuckerberg's apologies for upsetting users -- usually about privacy.
There are some common themes. Zuckerberg almost always tells users that change is hard, often referring back to the early days of Facebook when it had barely any of the features people know and love today. He says sharing and a more open and connected world are good, and often he says he appreciates all the feedback.
Most of all, Zuckerberg seems to take pride in offering an explicit, earnest apology, but doesn't actually admit he was wrong, just that he's sorry for how things were rolled out or perceived.
Of the 25 posts Zuckerberg has published on Facebook's corporate blog, 10 were to address complaints.
