I think I got it

Another great podcast. Thanks!

I think I finally got a way to put words on the differences between Display suite, Panels and Page manager:

• Display suite is a tool for managing view modes for entities.
• Panels is a tool for creating arbitrary layouts.
• Page manager is a tool for mapping paths against content (or responses), and also for pulling in contextual data.

Examples of how these modules work together

• Display suite is (for example) awesome for creating a special layout for teasers. This could be done using a Panels layout, but Panels cannot in itself affect how teasers are displayed. Display suite can also create new view modes, which the other modules can't.
• Panels is (for example) awesome for creating customized layouts on custom pages or blocks. While Display suite can change the layout of entities, it cannot affect other parts of your Drupal site.
• Page manager is (for example) awesome for adding new tabs on user pages beloning to users with a particular role, or on node pages containing a particular taxonomy term. Or for pulling in data about referenced entities when displaying a node. (None of this can be done with the other modules.)

Examples of how these modules overlap

• Both Display suite and Panels can be used to change the full view mode of entities. Display suite does this by altering the view mode itself, while Panels does this with the panel nodes. If used with Page manager, you can also override the standard entity page, having it display layout and content built with Panels (or possibly some other module).
• Both Dispaly suite and Panels provide Views with new row styles, allowing Views to output its result in customized layouts.

Another stellar podcast, gentlemen!

Incidentally, the "CSS3 selectors simplified" link appears to be broken (simply an extra URL at the beginning).

In the part of the podcast concerning the Smashing Magazine article about the three leading CMSs, there was some speculation as to why online searches for "Joomla" outnumbered those for "Drupal" 3-to-1. Based upon my experience talking with other freelancers and their business prospects/clients, I think the main factor is that Joomla is most popular with web site builders who are not hard-core developers -- much more so than Drupal. Consequently, the site builders approach prospects with proposals for building sites using Joomla, prompting the prospects to search for more information on it.
