Module, snippet - Help!

What’s the difference in these two and how do you decide what you need to create? I want to develop an AJAX appliaction, something like Digg.com, but I’m not sure how I should work it in with modX. Do I work create a new module or a snippet or what?

Thanks!

A snippet is for adding code to pages in the site. Consider it the MODx way of having <?php ..... ?> blocks in your HTML.

Modules are for adding features to the Manager without having to hack the Manager files.
