This doesn't interest me one bit because usually when i enjoy a game enough, i almost never use faq's and stuff. And also i am used to just going on gamefaqs when necessary...
However, it's not totally a bad idea. A lot of new users are getting into nintendo games with the DS and WII. I work with a bunch of non-gamer type who bought Zelda on the DS, and they asked me to bypass some parts for them that they just couldn't manage to do. This is surely aimed at these people and it's a nice initiative as i know, not everyone is as dedicated to gaming as i am. Good move for Nintendo, and i know they are facing harsch criticism from the 'hardcore' crowd for trying to appeal to the non hardcore, but well, see what the hardcore gave the gamecube for support. Long live Nintendo.
As far as seeing such an initiative on TTG's, i am personally not interested. The hint system works wonderfully as it is, and the games are never so hard that you couldn't find the answers for yourself if you wanted to.
