I only saw Steve Jobs twice, but he had a huge influence on my life at about 5 points that come to mind. I am very proud that such a person would come from Northern California, and Steve Jobs certainly represents the best you find in humanity. Really, the culture of Steve Jobs and the technologists somewhat like him (Charles Goldfarb, John Warnock, James Gosling, Larry Ellison, etc.) are to me one of the few positive spots when you look at global culture in this day and age: I'm sure there are plenty of common souls around the world, yet not nearly enough. Such people would stay up late envisioning new ways that humans would communicate, persist information, and render media, and their visions are keen enough that they become reality.
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?
