You can look at the changes on Twitter similarly to the advent of a graphical user interface that made its debut in early-1980s computers. The design was called WIMP and stood for “windows, icons, menus and pointers.” Before WIMP, the only way to use a computer was by writing code, something most people couldn’t even comprehend.
This isn't just oversimplification. It is just wrong. Before windows or pointers there was “user friendly” software. There was quite a lot of it.
