Early on in the internet age it somewhat bothered me that every page on the www either acts like it is the first thing one reads on a topic or assumes great knowledge of the subject. With nothing in between.

Wondering about a technical solution I couldn't find anything besides fold out explanations and links to explain jargon. Neither would really bridge the gap.

One obvious theory was to keep track of what the user knows and hide things they don't need or unhide things they do. This is of course was not acceptable from a privacy perspective.

Today however you could forge a curriculum for countless topics and [artificially] promote a great diversity of entry level videos. If the user is into something they can be made to watch more entry level videos until they are ready for slightly more advanced things. You can reward creators for filling gaps between novice and expert level regardless of view count.

Almost like Khan academy but much slower, more playful and less linear.

Imagine programming videos that assume the reader knows everything about each and every tool involved. The algorithm could seek out the missing parts and feed them directly into your addiction or put bounties on the scope.
