@strauss Great post and some quality content that you plan on putting together. So much of this needs to be done in my opinion and many of your points should to be done in future. My thoughts if you are just looking for a start would be:
Asch introductory video / animation:
A roadmap on the website that shows future milestones, not only past ones.
Show some information of at least a few team members on the website
Update Asch whitepaper. Many projects have a shorter version as well which is good for attracting more interest, faster to read and understand for many.
