SitePoint ran an article today that mentions wikis. The article is about hypertext — what it is, why it was invented, and how understanding it can help you make better webpages.
Here’s the article: “Caffeinate Your Hypertext“.
The article explains (very matter-of-factly) that hypertext and HTML aren’t the same thing. Hypertext is simply a text document that is — as the article puts it — caffeinated. HTML, on the other hand, is a standardized language used in creating hypertext.
I rather enjoyed reading the article, since it introduces several sites that are using hypertext in new and innovative ways. It lists the WikiWikiWeb among many others.
