Please bear in mind this is a scrappy demo, and is more about showcasing the concept than creating a beautiful demo.
Note - Please use audio to watch it.
The key premise behind this is that note taking apps are fabulous ways to store your own knowledge, so why wouldn't you share knowledge in the same format, and build a following around that. Anything, from a systematic review you've done on a scientific topic, to resources you've found useful on a certain topic, to things you've learnt from your work could be shared in the cohesive, structured format of note taking apps.
Furthermore, the idea is to publish refined sections of your notes on specific topics bit by bit, making it more readable to the end user and more focused. This is slightly different than the current digital garden approach to publishing notes, which is more about publishing everything.
Note - all the longer response questions are optional. I'd love to hear your detailed thoughts if you have them, but I appreciate you're busy, so feel free to leave them blank if you don't have the time or don't have too much to say here.
