{{MyTiddler}}

Double curly brackets indicate a transclusion. (the contents of another 
tiddler are brought in here)

I think that's wrong, or unnecessary.  Three curly braces indicates that a 
filter notation is inside the brackets that will be converted into a list 
of matching tiddler titles.

Two angle braces indicate a macro or a variable (they're actually the same 
thing, internally).
 

> and only one angle brace in front of $X here:
> <$set name=dateToday value=<<currentTiddler>>>
>     <$list filter="[tag<dateToday>]">
>         <h2><$link><$transclude field="title" mode="block"/></$link></h2>
>         <$transclude mode="block"/>
>     </$list>
> <$set>

The tags with <$ are like HTML tags, only with superpowers. They're called 
widgets. You can look up the documentation for most of them by appending 
the word "widget" to the keyword. e.g., Searching for "listwidget" will 
find documentation for the <$list> widget. Most of the things I described 
for {{, {{{, and << brackets are actually just wikitext short-hand for 
widgets that get called to do the actual work.

I've been working on a tutorial/book in my spare time, but think it will be 
awhile before it's ready ;-)

Eric Shulman has a book that you may find useful:
