WikklyText started out of a few of my personal desires:

• First, I wanted to experiment with doing more Pythonic things within a TiddlyWiki-like framework. An obvious expression of this is the ability to embed Python code in wikitexts. With this addition, wikitexts now have access to the full Python library, and issues like "how do I talk to a database?" become moot.
• Secondly, I liked the basic TiddlyWiki markup language enough that I wanted to enable it to be used in more contexts. I was tired of using domain-specific markup languages (hand-edited HTML vs. TinyMCE vs. reStructuredText vs. ...) and wanted to move to a single standard for my own content. To this end, WikklyText provides highly modular pieces for rendering, store management, etc., with the hope that others will be able to mix & match pieces to build their own tiddly-speaking applications.
