I don't think the search function is that great here, but I would point out that some specific questions (some that one would think would be commonly asked) are actually not asked. When I've had some questions I wanted answered (whether or not I ultimately made a new thread asking a question) I exhaustively searched this forum through this site, through google and bing... and it turns out everything isn't asked.
Also, the point of a forum is to discuss things in real time, and generate discourse/dialogue. If one question should never be asked again, then there'd be wikis/stickys biannually about equipment, and nothing more.
Also, I think patience should be shown with both new posters (many of whom probably may not return after their initial question is answered), and folks coming from places where their local expert resources (such as competent bootfitters) are somewhat to completely absent.
But overall I think we all know this place is much more friendly and civilized, compared to the shit-show going on at the TGR forums, where-God forbid-any new person (automatically JONGs and Gapers) could join... and overall it is more of a porn/perv festival than actual skiing talk (and of course the latter often dealing with extreme backcountry tours that many people just don't do and/or aren't in to)
