The knowledge contained in the articles is very good but I got the feeling that it was written for an audience that already undertands the problems being solved. The Stack for instance is written in a language that only really makes sense if you've spent a lot of time with CSS and contains some extraneous paragraphs. I only mention this as the problems and solutions being explored are very valuable to learn but I think it could be written simpler and more succinctly so that meaning isn't lost for new-comers.
I'd be happy to contribute if it was open to suggestions.
