I wonder where is the line for CRUD app - because of course CRUD became derogatory term for writing simple apps but HN or Twitter are basically CRUD applications. Heck Facebook is one big CRUD app.
Where Google search is not a CRUD app.
Serving music or videos online should be even easier apps because - well these are mostly Read so there is not much create or update.
Is it that derogatory term should be "simple crud app"? Because even CRUD app after integrating with some 3rd parties, getting bunch of features starts to become quite complex.
CRUD implies neither simple nor easy. It just means a web application that mainly front-ends database operations. That describes most web applications even if they have additional functionality.
