AP: Facebook no longer lets users hide from search
"Facebook Inc. said Thursday that it is removing a setting that controls whether users could be found when people type their name into the website's search bar. Facebook says only a single-digit percentage of the nearly 1.2 billion people on its network were using the setting."
While it might be true that a small percentage of users were using this privacy feature, we're still talking about 12 million people who'd taken the time to protect themselves for reasons that might well not turn out to be trivial. And it's likely more people would've used the feature, I imagine, if Facebook had publicized it more widely or made it easier to find and use.
