世論 What Japan Thinks

A recent quickie survey from iShare looked at file extensions.

Demographics

Between the 7th and 12th of July 2010 479 members of the CLUB BBQ free email forwarding service completed a private internet-based questionnaire. 56.2% of the sample were male, 31.7% in their twenties, 32.2% in their thirties, and 36.1% in their forties.

There’s not really much for me to add to this survey except that I know all the extensions listed below.
