StructuredText is a standard wiki page language; on wikis which use it, pages are edited in this language. It looks natural in its raw form and can easily be rendered into HTML. - http://www.zope.org/Members/jim/StructuredTextWiki/StructuredTextRules There's a variant of StructuredText called ReStructuredText: - http://docutils.sourceforge.net/rst.html TwicI doesn't use StructuredText; it has its own format, WikiText (well, TwicIText). At one point, it was thought that TwicI might move to StructuredText (or a close relative) in the future; it is now all but certain that it will not. StructuredText has too many features which suck badly, many of them stemming from its Pythonesque enthusiasm for significant leading whitespace (just have a look at the mess they're in over lists, for example). Spookily, StructuredText and TwicIText have a number constructs in common, despite there being no obvious common precedent and no interchange of ideas. In particular, the use of colons for tagged WikiLists is almost identical. CategoryWiki CategoryGeekery
