[sentenza]

Simple English does not work for non-native speakers and here is why:

Everybody is exposed to some English, but not all people are exposed to the same English. Every non-native speaker is using available media to learn the language, so you'll have people who know bad newspaper English, then people fluent in TV-Drama English and finally those speaking and writing "Broken English" (looking at you, facebook, 4chan, etc.).

So people will be _using_ non-intersecting vocabularies in their own contributions. They would actually have to learn Simple English as another skill first.
