But many of the things the author lists are not as basic as using a steering wheel. Why in the world would an average user need to care about when "www" should be in a url? Or even need to know when the term "download" is appropriate? Yeah, if you work with word and double-space things a lot you should know how to do that. But I haven't encountered many people who don't know how to double space. And yeah, at this point people should know how to google things. That's a little more problematic, but I rarely run into people who don't know how to use google at this point either. Some things on the list are important. A lot of things on the list are things that are minor annoyances that are likely similar to what my mechanic experiences when I try to describe my problem to him.
