maybe an outline of the various topics, with supporting articles written under each topic,, "with" links to information that is perhaps more deeply explained.
i like ghurds thinking in re to a multi tier
maybe the topics could have a simple writeup that a true newbie could make some sense of, followed by a group of links to elementary explanations, then follow with some intermediate article with intermediate level links, then cap it with some higher level article and links to support that level.
it would take a bit to set up, but there are many good folks on here, each chipping away at their favorite topic,, probably wouldn't take to long to see a real resource emerge in my opinion.
i know we all have favorite topics and area's of interest, along with dozens if not hundreds of links to all sort of info, from manufactures to white papers, diy'er reports to research center reports etc.
personally i think it would be worth the effort
i am working on an index of info from my own collection, nothing irritates me more than to come up with a question that i know i have the infomation on but can't remember which book, link or whatever the answer is located in or at.
at least i know the answer is in my collection, to a newbie they don't even have that.
