The problem here is it is absolutely not "more user friendly" to just automatically make things more WYSIWYG. When it is important to preserve content and structure rather than just presentation---as is <i>nice</i> in HTML generally but <i>crucial</i> on Wikipedia---you need to provide a tool that helps you do that, not just make it pretty.<p>I have a student who has just completed an honors project that demonstrated that if you give web novices a simple markup language and a <i>non</i>-WYSIWYG editor (but do give them a preview button) they confirm presentation but focus on content, which ultimately makes websites more usable and often prettier too. It won the ugrad research competition at SIGCHI this year, so I don't think she was out in left field on this.<p>So, short version: Wikipedia's making a big mistake here.
