initator of polkadot.study and frontend tutorial author here,
The lesson I learned from creating it is that even though there was funding available for authors (1500$ for a tutorial) it was hard to find them. I have the impression that curating authors and or even having in house authors for different tracks is a thing that is one of the most important aspects of founding a tutorials platform. Did you think about funding for authors? From my current point of view creating engaging tutorials (+videos) is difficult and needs lots of considerations as well as work afterwards on maintainance as you say. Shawn’s kitties tutorial really stands out here. Maybe creating a track “frontend” and then collecting ideas in on tutorials in the forum that authors can try to write.
I can imagine writing frontend tutorials or parts of them. I think building a full production ready application is a good content, that can be split in different modules each one concentrating on a specific lection in frontend dev with Polkadot (wallet connection, reading chain state / mutating chain state, subscriptions, …). I also hope that initiatives like a UI Component Library can reduce much boilerplate code for frontend developers. In my tokengated-next-js-tutorial a huge part was setting up contexts and providers for that purpose. That way tutorials would become easier for starters and better to maintain by outsourcing logic and ui to other libraries (papi, reactive-dot, ui-component-lib).
Thank you for picking up the mission of providing good developer tutorials for Polkadot.
