(keitai-l) What is a "popular" I-Mode or CDMAone site?

Hi Folks,

there are so much "popular" I-Mode or CDMAone sites out there, but what
exactly means "popular"? Are there any public statistics about 
usage of these sites? 

And how do you count these usage in this case? Ok, I-Mode can be 
measured also in pageimpressions and visits, but how about CDMAone 
sites? Pageimpressions doesn't make so much sense here, IMO.

Thanks in advance,

Juergen
