I'm always surprised when people say the site is dead/dying because every time I google anything regarding a game, I almost always get directed to GameFAQs and find the answer rather easily. Not so much the walkthroughs, though - it's mostly the Answers and the archived message board topics. Text walkthroughs are more difficult to justify these days, unless it's for keeping track of collected items and the like. I'd venture to say the issue is more in building loyalty towards the site and users actually wanting to be part of the community outside of having their specific question resolved.
