What seems useful to me is the ability to type in "function that takes the path to an image file and returns a new image file with rounded corners". These are not groundbreaking problems - I'm generally looking for solution out there that uses a popular library. This is especially useful if it's a language where I'm not up to date on the de-facto library of choise is for various use-cases. In most cases, especially while prototyping I'm not going to write it myself, nor care about which library - I'm far more concerned with some big picture goal. If someone builds a product that can do the work of Googling a solution for me, that's the draw of the product. The code is freely available anyway.
