WikiSwitcher

Prompt the user if there exists a better version of the current wikipedia article in one of the user's selected languages

Ideal for a multi-lingual internet user who wants to ensure they're getting the most complete information about a given topic on Wikipedia, The Free Encyclopedia. One common use-case is for articles about a regional topic or location. It is likely that an English-language version exists, but that the locality's native language will have higher quality or more information.
