Umm... I don't think so. If you are thinking of CS as in Computer Science then that is CS and what the list mentions is what someone who wants to work in IT would need to know. Computer science is much more than just web technologies and many many people on HN will testify they got jobs because of knowing what this list mentions I am not denying that there are many others who would say they got jobs by knowing stuff on the list in the link, but hey its just plain wrong to say these things do not get you jobs. Many university professors have this as a minimal requirements for their job, thats one example.
