Similar to how StackOverflow can have multiple different correct answers. It would be interesting if you could say build a REST API with the given requirements and each person links to github with their solution. You could then see how various different frameworks solve the same problem.
StackOverflow has Documentation.
Another nice resource is Rosetta Code.
EDIT: Also just noticed Rosetta code has a section for sites similar to it: rosettacode.org/wiki/Help:Similar_Sites
The idea is cool. Slant does something, but not really similar to what you want.
