In my opinion this question should be preserved even though it is bad, because it has nice answers worthy of preserving. To pick one example, I personally found idea of sleep sort to be rather enlightening in the thinking-outside-of-the-box kind of way.
The Question should stay locked. It is historically significant despite being a polling question.
Despite a few smart-aleck answers, there are some good answers in there. Most of the suggested algorithms are "non-traditional" which can be useful for learning from when a project has unique requirements. It's not mentioned in the answer, but BCrypt is an example algorithm that's been intentionally designed to run slower in order to hinder brute force attack.
The Question should be deleted, it is a bad question and we should all feel bad.
