Reading some info on some threads over here regarding skills it came to me, that 4e could explicitly treat knowledge as a kind of equipment one can seek to "buy" or better gain. Before entering an adventure location, knowledge could give for example a bonus to perception rolls among other things. And as cursed items it could also happen to provide penalties instead until misinformation is identified. Then there could be pieces of knowledge that one should need to have other pieces to "activate" them and these "pieces" should be of two categories: medium and subject. Moreover a medium could be activated after x period of dedication (ie reading a book-tome).
So what do you think?
