I think these styles of puzzles borrow a lot from competitive programming (e.g: ACM, IEEE). And while competitive programming requires skill, what you do most of the time is collaborative programming: create software that interoperates with other software, with a user, that is maintainable, etc. Software without these skills quickly becomes really expensive and hard to maintain.
