Interesting data from Google on mobile phone search queries from this Google paper to be presented at the CHI 2006 conference:
* one in five mobile searches have to do with adult entertainment (about twice the rate non-mobile of adult searches)
* mobile query text strings are as long as the non-mobile query text string
* it takes cell phone users, on average, 60 seconds to enter a search term and get results (wow, that’s long! I think I’m a bit faster, though I’ve never actually timed myself.)
My best mobile search story is when I couldn’t remember the details of a joke I wanted to tell someone and I was able to search for it and find it in the first page of results on Google Mobile (it was a long query string: “golf clubs dessert island joke”).
