Even if it's not always the best markup, what are Facebook and Twitter? They're web standards with some scripts. They may not validate, but they're still CSS layouts and simple markup, and that's great!
What we now call the browser is whatever defines the web. What fits in the browser is the World Wide Web and a number of trivial standards to handle that so that the content comes.
World Wide Web: Proposal for a HyperText Project
This coined the term “World Wide Web”. The co-author of the document was Robert A Caillau.
Now I am not against widgets, those small third-party applications that people can put on their Web pages on social networks like Facebook and MySpace, in general.
The story of the growth of the World Wide Web can be measured by the number of Web pages that are published and the number of links between pages. The Web's ability to allow people to forge links is why we refer to it as an abstract information space, rather than simply a network.
If someone had protected the HTML language for making Web pages, then we wouldn't have the World Wide Web.
The Web as we've known it for a long time has been pages linking and pointing to other pages.
Basically, we convert the entire Web into a big equation, with several hundred million variables, which are the page ranks of all the Web pages, and billions of terms, which are the links. And we're able to solve that equation.
In comparison, Google is brilliant because it uses an algorithm that ranks Web pages by the number of links to them, with those links themselves valued by the number of links to their page of origin.
If you look at how many thousands and thousands of pages, Web pages, are being added to the Internet every day, it's the fastest growing organism in human history for communications.
When you close a tab or when you finish an article on the web, it's gone unless you go back into your history or search for it or explicitly try to find it. Apps on your phone have this special property: they hang around. In some ways, they're more like a book on a bookshelf than they are like web pages.
