Usability is generally trumpeted as a major consideration in website design. What is often ignored are the results of a website losing its usability – or, indeed, its familiarity. Yesterday, a number of users were unable to log on to Facebook. Why? Because they weren’t actually on Facebook.
What happened was that, for a couple of hours, Facebook slipped off the top Google rank for the search “Facebook login”. Instead, a blog called ReadWriteWeb (an excellent read, by the way) slipped into first place. Not noticing the change, users simply clicked on the top link anyway and were taken to a ReadWriteWeb article about Facebook, which looked entirely unlike the actual Facebook page.
