Classical Plone Theming
You can easily change CSS (colors, sizes, fonts);
More profound changes can be done by customizing “views” and “templates”;
Even more profound customizations: modify the main template
A lot of work for radical design changes!

What is Deliverance
HTML theming tool:
“Shifts around” HTML

How does this work?
It's a separate server which you put in front of your (or any) webserver.

Yes, but how does this work? Merge Content and Theme as specified by Ruleset.

Advantages
Graphic designers don't need to know Plone;
You can easily use a 3rd-party layout;
Separate interface for content management;
Keep your Plone site as basic as possible;

Disadvantages
Extra layer of complexity;
Separate interface for content management;
No more WYSIWYG;
Extra server (maybe);

Caveats
Deliverance does simple find-and-replace, no complex transformations
Tell graphic designers which HTML Plone produces, or have them take a look at a Plone site beforehand
404's unstyled
Beware of compression (CacheFu)

Performance considerations
Deliverance is fast, compared to Plone
It will not make your site any faster, because Plone still has to render the page
But your performance won't suffer
Lighter HTML/CSS/JS may save bandwidth and client rendering time

When to use Deliverance
When you are handed a ready-made design from a 3 rd party;
When you want 1) full Plone functionality (for editors), and 2) a specific design (for viewers)
When a design would require slightly modifiying many templates / views all in the same manner;
When you have more than 1 content source;

When NOT to use Deliverance
If you want to keep WYSIWYG;
If you want to do a simple graphic design alteration;
If you're going to customize all of Plone anyway;

Ways to use Deliverance + Plone
