Comparing Markdown and Creole as Markup Languages

At the moment I opted for Creole but I'm not sure whether this was decision has a future as Creole development stoped a few year ago (The Creole is live press release is from 2007!) and Markdown is still active (The most recent news is from 2009 :-( ! not so recent any more, actually). Moreover markdown is integrated into Django. Some more differences important to my application are listed in the table below.

feature	Creole	Markdown
Link	http://wikicreole.org/wiki/Home	http://www.freewisdom.org/projects/python-markdown/
Tables	colspan and rowspan not allowed	colspan and rowspan not allowed
Macros/Extensions	Macros can be easily handled from Creole text	Extensions are probably a more powerful tool, but more complex to handle
TOC	I already implemented table of content as a macro	Table of content is an extension that I didn't test so far
References	I Already have an idea how to implement references	A new extension is necessary, probably

More Markdown feature not so important at the moment are listed here. Definitely I have to learn how to write extensions, so I can improve my pythoknowledge and evaluate the efforts necessary to write or change an extension.
