I'm surprised it's continued for so long! I've been doing web dev for 30 years and never felt the need to read a text or even watch a video, for me it's just all available in text on the web and always has been because the people building the web are using the web to do it.

I bought some books to support A list Apart, but most of the content seemed to be an aggregation of stuff that authors were already writing about before/after.
