Feature suggestion: "Suggested next topics"

[jruales]

Feature suggestion:
Finding the "fringe" of the learned topics subgraph for a certain user and displaying this list of nodes in a user's profile. This way, a user can have a list of topics for which he or she already knows all the prerequisites, but doesn't know the specific topic: a "suggested next topics" list of sorts. This list could be ordered so that the hardest topics (the ones with the learning tree of most height, or with most nodes) come first.

Just sent this exact request. Wish I had seen this first.
