Oh, I'm completely behind the "little modular add-ons" concept; in any software (or heck, many systems), that's a great thing. I like the Drupal way. I'm only a little surprised that custom teasers separate from body text – which for 5.x, does require a third-party module – wasn't automatically something everyone wanted. No complaints here, just a friendly "huh, that's interesting!".

But a question: Is there a Teasers module? In my 5.x installations, I see nothing with that name in the modules directory... Am I missing something, or is Teasers not the name of the module that handles teasers?

Thanks for the comment! Some very good design background for Drupal newbies who'll read this.
