For the 20th anniversary of Haiku, I propose the Team make an interview with those who stood with the project from its inception: Michael Phipps, Axel Dörfler, Stephan Aßmus, and all others.
Also, it would be great to write a follow-up article with the current state of things in Haiku to this one https://spectrum.ieee.org/computing/software/the-dawn-of-haiku-os.
Then, the team and the community would promote both the materials (including their translations to other languages) over the net.
