for a marketing ploy (the ads for ipods etc are what fund it) this is actually a really good idea
even if you “cheat” by using dictionaries everyone wins as you learn stuff, the people in developing countries get fed and there is more time spent on the site which makes the advertisers contribute more
I think this is really good for people in other countries particularly places like Singapore where they want to learn good English, have constant access to the net but are culturally and politically discouraged from getting involved in other forms of activism/direct action….
