I just discovered runnable.com. I've noticed that a lot of the examples that I've looked at are poor quality code, and don't necessarily do exactly what they claim to do, or have variables or functions named in such a way that it makes things less obvious and more unclear. has any member of this forum contributed code or offered constructive advice to users who have posted bad examples? do you think it's worthwhile to contribute to such a thing, given that the majority of examples are likely to be submitted by people who are themselves just learning?
