Nice product! I agree, TFA's author doesn't seem to grasp that some tasks, with constrained inputs and outputs, might be better served with a well-designed visual tool. ETL (like Yahoo Pipes and your project) seems well-fitted. Decades ago I built children's literacy software. I built the building blocks (sometimes visual sprites, sometimes behavior blocks), and the artists and educators took those building blocks and built a series of products. It worked nicely.
