Not only does the differentiation of terms create a divide within the industry, the term ‘web app’ regularly acts as an excuse for corner cutting and the exclusion of users.
We kid ourselves into thinking we’re building groundbreakingly complex systems that require bleeding-edge tools, but in reality, much of what we build is a way to render two things: a list, and a single item. Here are some users, here is a user. Here are your contacts, here are your messages with that contact. There ain’t much more to it than that.
