Well, there are a few things that I'd like you to keep in mind.
First, I think we can discuss this topic with civility, as you have in your post.
Next, remember this is the first article in a two-part series. The second article does drill down more. But not everyone who comes to the site is as seasoned as you and lopossum. A large part of our readership is moving from power user to developer and wants this type of information. And one of my goals is to help as many people become Mac developers as wants to.
Also, please remember that the contributions to this site come from members of our audience who are not paid very much and give freely of their time because they believe in this platform and want to help others master it too.
There is certainly the detail you want in our O'Reilly books, which we spend countless hours working on and at great expense. They are available through our Safari online service and in bookstores everywhere.
This site does not have that kind of budget. It is free. And it is dependent upon the people who contribute to it. I thank every writer who publishes on this site for his or her time. I think our audience does a great job of providing us with interesting, topical content.
Finally, I've learned that when I publish content for both beginning developers and seasoned veterans, the site is more vibrant and has more traffic. When I publish only the in-depth stuff, traffic wanes, and if it stayed that way, the site would be in danger.
