Wikipedia has some severe biases when it comes to what and who counts as notable. For instance, you can compare ”programming pattern” and ”knitting pattern” and try to guess which is a 50 year practice and which is as old as civilization...
That sort of topic bias is best solved by adding new contributors, but they will intrinsically have to be different sorts of persons, and historically that difference has caused issues for the newcomers: https://www.nytimes.com/2019/04/08/us/wikipedia-harassment-w...
An example - there are pages which are not fleshed out as much as programming patterns such as childcare or kindergarten education which are commonly viewed as stereotypically gendered but which in reality all parents regardless of gender are actually interested in and write about.
