What opensource CMS: generates clean xhtml, is skinable with css, and has a lightweight markup content editor?

Question

See title. By lightweight markup I mean something like markdown or wikitext.

Answer 1

Well, silverstripe http://www.silverstripe.com/ is thought to be a good option for people who care about web standards , as is modx http://modxcms.com/

For a lighter editor, check out textpattern.com which uses textile (like markdown). If you're on rails, http://webby.rubyforge.org/ might do the trick.

http://www.madebyfrog.com is a port of the ruby CMS radiant that aims to be fast, light, and minimal.

Answer 2

WordPress keeps getting better and better.

Answer 3

I'm loving modx.

Answer 4

I am a user of Joomla. I think Joomla is in the top five CMS.

Answer 5

I like Radiant CMS. Simple, easy to use and flexible, and it has markdown filters integrated.

Answer 6

Umbraco asp.net c# cms

Answer 7

Plone meets all those requirements, although it would be unusual to use markdown. (The underlying Zope platform definitely supports markdown, but in the Plone user interface, it's more usual to use the Kupu editor)

Edit: Since I wrote that, things have changed. Plone still supports Kupu, but these days you also have the option to use tinymce as your markup editor.
