Talk idea: a dozen possible "wikitext 2.0" proposals, a dozen different ways future wikitext and templates might look. Maybe a panel discussion -- here are a starter dozen, bring your own!

1. ArrayFunctions, etc: what a templating system based on handlebars/mustache/array functions might look like
2. Versioning: a clause at the top of the article that would let you opt-in to new features, like "backtick for <code>"
3. Grunge, a wildly simpler wikitext
4. Heredocs
5. Ditching the colon in parser functions / parser function & magic variable unification
6. Markdown! (Real question is: what would the transclusion syntax look like?)
7. HTML (wikitext is dead, long live the MediaWiki DOM Spec and Visual Editor)
8. Abstract Wikipedia (let's not write at all! / how does one "write" in a language-independent way?)
9. Language Converter on steroids -> writing in all languages at the same time.
10. Annotations everywhere
11. A composition grammar for transclusions / a world of fragments
12. PageMaker? More explicit control of the different elements of the article, with different languages (potentially) for each.
