I think it's valid to ask questions like this. We get advice all the time warning us not to try to invent our own algorithms for certain things. Obviously if we all did that, though, we would make no progress as programmers.

I'm not really an expert but it looks like this algorithm does sorting in a way that doesn't require as much extra memory as others..? I could be wrong about that, but the point is that this algorithm likely has some certain situations where it performs better than others.
