Having worked a lot with offline-capable apps lately, I started to see similar trends everywhere. Of course, that is partly because of frequency illusion, also known as Baader-Meinhof phenomenon – “When a thing you just found out about suddenly seems to crop up everywhere.”
Nonetheless, offline is really trending. As broadband connections and 4G cell phones become commonplace, and everyone and their mom talk about IoT, streaming and The Cloud™, it might seem strange to focus on the eventuality that you would temporarily lose your precious connection. But I find it perfectly reasonable. The more we get used to online services, the more we depend on them, and the worse the damage done when they unexpectedly stop working. Considering and handling offline scenarios is proactive damage control.
