I like the idea of a structured, science-driven approach to making the on-boarding better very much!
But it is a pet peeve of mine that sciences – and especially social sciences – are for some reason taught that only quantitative methods are “real” science to the point, where they totally neglect qualitative methods.
In your specific case: Creating the task list for your survey is a very non-trivial thing, where you should do something like (expert) interviews, open calls for suggestions, …
At first, I thought that this is only a minor issue with my pride, because I have some ideas about what people should learn early on, myself. See, for example: Better Introduction for Newcomers? or “My ADA are gone!” First Aid Collection
But then I looked at the task list you provide as an example at Ideascale and I’m a bit surprised. There are a lot of items on that list that should specifically be there, because I never would have put them there. I have more or less ignored Catalyst, because it’s just too hard to assess the flood of proposals (and as you guessed correctly, I didn’t have an Ideascale account until a few minutes ago).
But: Whole areas of topics – which are arguably much more important than the things surrounding Catalyst – are completely missing. There is nothing about wallet apps, wallets, seed phrases, transactions, (E)UTxOs, nodes, pools, native tokens, decentralised exchanges, Plutus contracts, order books, liquidity pools, technical and social security risks, financial risks, … in this list. And these are all topics that are quite or even very important for new users of Cardano. Why is there Discord in the list, but not the forum, Telegram, or Twitter? Why is Miro even in that list?
This can all be fixed, but I feel that it needs a whole phase in your proposal, a phase with extensive research and not just:
