Something small, but grabbed my attention nevertheless. Recently, I consumed the same Facebook update across both my web news feed and my mobile news feed. In this update, one of my friends added a place of employment to his timeline. What was interesting is that in the web news story, I had the ability to like or comment on this story. However, in the mobile news feed, I did not have the ability to like or comment on it. Most likely, this was a miss when implementing the same feature for the iPhone app.
