I just set up a basic Web site (WordPress blog) for a friend, Paris Tompkins. This took only a few minutes' spare time, including the hosting, DNS, customization. She chose the theme herself; I just made the side look OK and added the vital "Add to Any" plugin.
I still barely know WordPress, but I have had almost no trouble with any aspect of it recently: I played around with various blogging software about 8 years ago, and it was nowhere near this easy. I have only had to do something with PHP within a WordPress site once, and probably because of the nature of the template.
I have been working with XML since it was a glimmer in the eye of Jon Bosak. In fact, before XML was conceived, there was SGML; this evolution of SGML represented a streamlining for the web, but at its core there was not much functional difference; in fact the new invention was defined as a mere SGML subset. The key concept of semantic markup is central to the core value of SGML as well as its "streamlined for mass consumption" child.
The two main perspectives I have seen are Document-centric and Data-centric. SGML initially appeared in support of document-centric work: managing all the technical documents or contracts of IBM or Boeing, for example. Charles Goldfarb has maintained that "SGML literally makes the infrastructure of modern society possible" and I think he's right - hmm, should we blame him for the lengths to which humans have gone to destroy the earth?
