Substance is more important than style.
The use of graphics should be minimized, so pages load fast over slow links. We like to leverage the work that GNU volunteers have done at their own web sites as much as possible. There's no need to write an article from scratch if someone has already written something suitable. But often we want to adapt and modify the text. Therefore, we generally copy the articles we really care about onto our server, rather than making links to them.
