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...
The approach, tone, use of sources, etc. should be exactly the same when writing about design patterns and knitting patterns (actually, I have the feeling pages about knitting patterns will be much more sound and factual than those about design patterns- but that's only a specific case...).
