iShare Inc. did a research on their e-mail magazine readers.
One of the interesting results was that when they were asked "what does www mean?" 47.0％ answered laughter not world wide web.
In the age breakdown, 61.2％ of the twenties and 43.1％ of the thirties replied they think it means laughter not world wide web.
Q: What does www mean?

In Japanese, laughter is "warai" and people often uses "w" for laughter, "www" for more laughter, "wwwwwww" for a big laughter, etc.
You can see the whole survey result here though it's in Japanese.
I couldn't stop laughing when Evan Williams twitter this:
I think at least some of them were the Japanese trying to find funny stuff :P
And the post they'd find would be this :P
