The new apps are the result of a major restructuring happening inside Facebook. In recent interviews, Facebook executives said they have retooled the organization so that every product team is working on mobile, and the company holds weekly training courses on programming for Apple and Android devices.
Facebook engineers say the changes to the apps were necessary to deliver the instant gratification that people want when they are on mobile devices.
Facebook’s iPhone and iPad apps were so slow and laggy, I gave up on them many months ago. Let’s hope this move gets other companies using HTML-based apps, like LinkedIn, to change their tune as well.
