I'm experimenting with this as well as I'm layering TinyMCE over a wiki for my side project, Bibdex (dev image <a href="http://bibdex.org:8080" rel="nofollow">http://bibdex.org:8080</a>). I have tried extending TinyMCE with a wiki syntax parser. However, I'm unconvinced there is real value in confusing the text with magic syntax, with one exception.<p>Wiki markup is mostly cosmetic, so you can throw all of it out--except for auto-linkification. Linking makes the wiki.<p>This was easy with CamelCase links, but much harder for free links or other types of links.<p>I do wonder if it's possible to train people to use exactly one syntactic form, the square brackets.<p><pre><code> [words] -> free link
[http://url text] -> descriptive link
[http://url] -> escaped link (useful to pick up trailing punctuation)
</code></pre>
Presumably when you write a left square bracket, a floating div could appear with contextual help and auto-suggest.<p>If others are interested, I'm happy to share my efforts.
