Stepping back from technology for a post, here’s a really good, simple idea. Wikipedia as a resource is sometimes good, sometimes misleading and generally always useful. But, it’s explanations can be a little dry.
Simple English Wikipedia offers cut-down, simpler definitions for its subjects. Here’s an example of the first paragraph of both Wikis for HTML – the code of the internet:
HTML, which stands for HyperText Markup Language, is the predominant markup language for web pages. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists etc as well as for links, quotes, and other items. It allows images and objects to be embedded and can be used to create interactive forms.
Simple English Wikipedia:
HyperText Markup Language (HTML) makes web pages display properly on the Internet. It is a markup language, which means it has a mix of a normal language that people can read and a special programming language that tells computers what to do.
All the information you need is still there in the second definition, but in an easier to digest form.
