Whoops, I owe an apology to the Swedes: the Swedish Wikipedia
is bigger than the Icelandic, even if you take the number of
speakers into account.
I also wanted to say that I agree that gerard Meijssen's point is very
important: The wikipedias are indeed culture-bearers for their
respective populations, and not just for humanity as a whole!
The Esperanto wikipedia is a good example of just this. You'll find
plenty of articles there with information which might be considered
vanity, or at least not encyclopedic enough, in other languages'
wikipedias.
