I don't think that's as big a problem as you find it, currently. Maybe you just chase down more topics than others.
There is definitely an abundance of introductory material on the internet, but more importantly, there is an abundance of topics people have never encountered and ooh/aah over decent introductions to. Just assume everything you find accidentally is introductory.
However, as the niches get filled out, in-depth articles and commentaries may start emerging. At that point, a difficulty ranking system will have to emerge, and the associated conversation will fall naturally in the same difficulty category. A more relevant problem, imho, would be connecting the more demanding material to the introductory stuff without subjecting people to discouraging information deluge, draining directory shoveling, or a shallowing wikipedia scatter effect.
