Liquid is a template engine which was crafted for very specific requirements

It has to have simple markup and beautiful results. Template engines whichdon't produce good looking results are no fun to use.
It needs to be non-evaling and secure. Liquid templates are made so that userscan edit them. You don't want your server running code that your userswrote.
It has to be stateless. The compile and render steps have to be separate, sothat the expensive parsing and compiling can be done once; later on, you canjust render it by passing in a hash with local variables and objects.
It needs to be able to style emails as well as HTML.

Stuff to read, watch, etc.

You want to allow your users to edit the appearance of your application, butdon't want them to run insecure code on your server.
You want to render templates directly from the database.
You like Smarty-style template engines.
You need a template engine which does HTML just as well as emails.
You don't like the markup language of your current template engine.
