Simplified Map-Reduce model: WebMapReduce offers the features of Map-Reduce that are crucial to the core concept, without details that add to the learning curve.

Extensible language support: Mappers and reducers can be written in practically any language. All that is needed to support a new language is a simple wrapper library, possibly with an API for users to easily perform common tasks such as string processing.

Adaptable APIs: In addition, preincluded languages can be customized to alter their APIs—for example, in order to support libraries already introduced in a class, or to suit a particular teaching style or programming paradigm. Purely functional, imperative, or object-oriented strategies are all fair game.
