For example, I’m using Debian, and I think we could learn a thing or two from Mint about how to make it “friendlier” for new users. I often see Mint recommended to new users, but rarely Debian, which has a goal to be “the universal operating system”.
I also think we could learn website design from… looks at notes …everyone else.
I like that Spiral Linux is “plain” Debian, without extra repos. What I’m thinking is more along the lines of “why is Spiral Linux needed to begin with?” Sometimes downstream distros serve a niche function that warrants its own distribution, but sometimes I feel that if upstream improved, the need wouldn’t be there to begin with.
