I had the same question opening this thread so I googled it.

the interconnected nature of social categorizations such as race, class, and gender as they apply to a given individual or group, regarded as creating overlapping and interdependent systems of discrimination or disadvantage.

I’ve read little to no ubuntu documentation (aside from stuff like installation and very basic troubleshooting). Have you noticed any improvement to it? I think this post is 2 years old so I’d assume there’d be at least a bit of little change.
