Since the birth of Facebook, public posting has been the default method – until today, that is. In response to continuing calls for user privacy, Facebook is changing the default privacy settings to “Friends Only,” meaning that upon first registering for the network, your post will only be viewable by your friends. It’s a strong message sent by Facebook, a network that’s seen its stock slip lower in recent months relative to “secure” messaging apps like SnapChat. Whether the move increases consumer confidence, however, remains to be seen.
