I have another idea:
I love to learn new stuff in general, but even more about bitcoin/blockchain/btcProtocol/... these days.
I also think that knowledge will be increasingly important, without it the cryptocurrency as a hole can not grow as well as it would with more knowledge, because less knowledge means more people falling to scams, but not only that, it means less focus on decentralization, and other not so trivial things
But there are 2 problems: after some time reading and learning about things you find everywhere like difficulty, HDWallets, p2sh, importance of decentralization... it begins to be more difficult to find new material that is
a) new
AND
b) easily understandable with the knowledge one has acquired until this point (meaning: the new-stuff should not have to much new in it, or I won't have the time to understand it in the time I have)
=>
It would be great to have a quiz-section (flashcard-like): one could go through some questions once in a while and if they are done in way that they build on each other (knowledge wise), than I could gradually learn more every week.
Then give incentive to (in decreasing order):
1) the creators of quiz-series (depending of ratings/likes)
2) the people posting good quiz hints (memrise.com for example has the cool-feature, that lets users create hints, and even lets user users "like" the hints that help them understand/remember items)
3) the people achieving good quiz results (it wouldn't even be that of a big danger if people would post results on the web, because people would often read the answer when copy&paste and thus learn in the process)
Of course the quiz should be taggable (btc-protocol, sidechain/treechains, importance of decentralization, btc-101, btc-102, btc-python-step-by-step, ...)
BONUS) Maybe the creator of such a quiz-tool could be incentivized as well, a little bit for having build some working tool and additionally if the tool reaches an amount of x users or x-quizzes solved
Let me know in this forum or via private message (I hope you can see my private-mail, if not.. I am also btc_revel on reddit) if you are interested in some help. I might be interested in doing 1), 2), 3) and even the BONUS (developing the quiz-tool)
