Don't you think a mobile version of WTM would be an ideal time killer while in the train, at the airport, or any other place where you generally are wasting time? I think it would be a very nice addition to an already addictive quiz. On my Nokia N85 I can use the site, however, there's a lot of extra content which is usually not needed on a mobile website.
this app-thing is stupid. a whole bunch of people will stay outside when it's coming to an app. just a simple but efficent wap-site will work fine for all I think.
