Learning the gender of Dutch words

It is hard to learn the gender of all the nouns of the Dutch language. There are so many nouns. There are three genders; masculine, feminine and neutral but practically masculine and feminine are mostly the same.

People who are not originally Dutch can be recognised because they always get "de and het" wrong. A really simple program could make reading a Wikipedia article a training exercise. All it has to do is to remove the words "de" and "het" and make it a toggle for the reader.

The objective; having more readers for the Dutch Wikipedia AND giving them an additional reason to do so. Many people are learning to write Dutch and they are often subject matter experts in areas where this Wikipedia is weak.
