What is the best way to customize Thematic?
The only recommended way is to create a Thematic child theme.
You should never modify files in the Thematic theme directory. This is because modifications you make directly to Thematic will not survive an update to the parent theme.
What is a WordPress child theme?
As of WordPress 2.7 a child theme is a theme that inherits the style.css, functions.php, and templates of the parent theme designated by the child’s style.css file.
You can easily start one by copying the thematic-sample-child-theme folder from the Thematic theme one level up into the into the themes directory.

How do I choose a layout for my child theme?
One of the first steps in creating a child theme is choosing a layout. You can browse the layouts that come packaged with Thematic in the “library/layouts” folder. Once you have chosen a layout, import it in your child theme’s style.css. For instance, if you want two sidebars you need
@import url('../thematic/library/layouts/3c-fixed.css'); but if you want one sidebar on the right (default thematic) you need
How do I customize the look of my child theme?
Whether you want to alter the style of an element or completely remove it from display, CSS is the best way and your child theme’s style.css is where you want to make your customizations happen. You can use Thematic’s dynamic body classes to make changes to specific posts, pages, categories.
How do I make changes beyond what CSS is capable of doing?
Sometimes we don’t just want to hide something with CSS but remove it entirely. Other times we want to add completely new functionality to our child themes. These things are what our child theme’s functions.php does best. Almost every functional aspect of Thematic is changeable via hooks and filters.
Still not enough… if you desire to drastically change markup as well as functionality, you can add WordPress Templates to your child theme directory and they will override Thematic’s templates.
Where are all those action hooks and filters located?
Looking through the Thematic themes’s templates, functions.php, and the library directory can be daunting.

Why aren’t Page comments showing? How to enable them?
By design, Thematic turned off comments from pages by default. You can enable them on a per page basis. In the admin, add a custom field key of comments with a value of comments to the Page on which you want to have comments displayed.
