I have very little experience with the other sections, but I have some comments on the operating system secrion.
I would highly recommend staying away from Ubuntu, they are making quite a few questionable decisions when it comes to developing the Linux ecosystem which do not lend well to their continued openness and favorability.
I also couldn't help but notice that all the distros that are represented are Debian based, I would probably throw in fedora Linux for begginer friendly and bazzite for the gaming crowd although I do believe a decent amount of the maintainers are american. I also found it interesting that there was no section for moderately technical people, in which case the arch distros should be included, ie endeavoros and cachy os.
