My first reaction to those reviews was that they read pretty disrespectfully. Writing a book is extremely challenging and some of the feedback is not appropriate for a page that's associated with a standards body.

Then I wondered, "If these are the resources to avoid, where do these people recommend I find the good information?"

Alas, those links are mostly broken.

As a long time programmer recently learning C, I've been surprised by how prickly and unhelpful C culture tends to be.

The concensus seems to be that no published information is good enough, and none of the critics are willing to publish the good information.

Maybe I just haven't found the right groups?
