I see what your saying. I think there is a fuzzy line there between whether you should start a new thread or bump the old one. Personally, i think if you search and find a thread that is (closely) relevant to what your looking for and you have a question to add (not a comment or an answer to a year old question) then it should be ok to bump. (and i think it is usually ok) If you are answering a question that was posted years ago, adding a comment, or posting something not related to the subject, then it should not be ok, you should start a new thread then. This still leaves a bit of a fuzzy line though, maybe we should just say don't bump threads more than 3 months old, regardless of relevance (except for stickies) or something of the like. Quite a few other forums i've been to have a rule like that one. I guess the other solution is to just accept both of those near that line, especially for new members. If something is on page 185 of the general discussion thread, i think you should be excused for starting a new thread, unless of course it appears in the search, or if you are supposed to talk about that subject in the general discussion, in which you should have added it to that.
(that's got to be the longest post i've ever done here)
