Incremental learning. It's come out of the spaced repetition movement (SuperMemo really). The algorithm presents you with something that you flagged as interesting. If you're truly interested, you engage with it (and notify the algorithm) otherwise you move on to the next subject/item. It doesn't solve the problem of having too many subjects/areas but it does allow you to keep a running list of items you want to explore. Incremental reading [0] is the source of this approach, but spaced repetition like approach can be used anywhere, including learning.
