Newspeak

Orwell has, yet again, proven himself.
In 1984, his imaginary world has a language that is becoming more and more simplified each year, as the authorities replace words with bad connotations with the opposite of words with good connotations.
Wikipedia has a new function where one can actually change an article into "simple English"-- English without "big words". Here's the link for the descriptor page.
Wikipedia says they designed this for "people with different needs, such as students, children, adults with learning difficulties and people who are trying to learn English." I understand that Wikipedia would see the need for this, but at the same time it alarms me slightly. I have always been taught that you never learn by having things be easy for you, but the case about people with learning disabilities and those trying to learn english really struck a chord with me.

What do you guys think? Have you ever encountered a Wikipedia page where you weren't able to understand it because it was too difficult?
