Rosetta Code

Today I'd like to suggest the interesting Rosetta Code site:

Rosetta Code is a programming chrestomathy site. The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another.

Since the R coverage of the different tasks is still largely incomplete, I encourage everyone to populate the missing tasks with appropriate R code.
