We have become accustomed to casually giving up factors of two or ten or more with our choices of tools and libraries, without asking if the benefits are worth it. performancesoftware
Locus. (Appwalls) An Article by Ethan Marcotte ethanmarcotte.com I’ve noticed a recent trend on the web — or at least, on the parts of it I’ve visited. Maybe you’ve noticed it too. Here’s what happens: you’re on a website, and one of these little prompts pops up...[to] let you know that there’s an app, and that the website you’re on...well, it’s not quite the app, is it? ...Sometimes, the website wants me to install the app — no, it needs me to install the app. It’s like a paywall, but for apps. An appwall. In recent years, these prompts have gotten more prominent, and occasionally impassable. And I think that trend’s interesting. Why would a company promote a native app over their perfectly usable website? It feels like a glimpse into that company’s design priorities. And it’s possibly providing us with insight into the business value they place on the open web — a medium that’s meant to be accessible everywhere, on any screen, on any device. And it really does feel like these glimpses are becoming more common. wwwux
