What's that? The sound of Facebook listening to its users? Good grief!
So, rather than having some hideous automated random content generator sort the newsfeed, users can now change back to 'Recent Stories First'... which is a good thing. Not least because the immediacy of Facebook and being able to react to what other people are doing is part of the reason that it made sense. It was simple, it was easy to understand and sorting things by how recently they'd appeared made sense.
No, this isn't exactly earth shattering news, but it does show how important the little stuff can be when it comes to usability and people's interactions with technology. And how important it is to respond (in a timely fashion) when you're being told by your user group that something just isn't working for them.
Those are the lessons worth learning. Regardless of whether or not Facebook features in your life. Getting the little stuff right is always important.
