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.
Well, I don’t personally need the new user friendliness, I’ve used Debian for the last 10 years or so, but I do think it’s an area we could be better.
