I confess that Post Formats as it has been implemented in the Core for several WP-versions, and WP-v3.6 in particular (hopefully to be released from the trauma ward here shortly...), which was to showcase a new User Interface UI for the PFs, also built into Core ... have been a notable head-scratcher for me, which judicious scratching has not relieved.

Post Formats, as presented, are reminiscent of slightly enhanced Microsoft Outlet Express Stationary. "Yer kidding. That's it"?

In operation, they appear to yield a stripped-down, even dummied-down Post. This has not been a need that I noticed calling out for a solution ... to fragment the various content-elements that make up a nicer, more-interesting Post, and then post the scraps as posts themselves.

So honestly, like an unknown sleeping dog, I largely steer clear. We will see in due course, what kinda critter it actually is.

The plugin WP Awesome FAQ, given a quickie-pointer here, creates a FAQ-page, by creating a custom Post Format (instead of clicking on stationa...). FAQs are a data-tuple (two pieces - the Q and the A), which is close to as simple as data-structures can get.

The zip download for the plugin is under 80K, and nearly all of that is the two screenshot-images. The code-file for the plugin is less the 3K, consisting of a mere 70 lines of PHP.

This is a very simple little program, with which to get some inititial hands-on, nuts-and-bolts familiarity with the actual mechanism behind Post Formats (and how to create custom examples) .... which the debacle of v3.6 convinces me to start doing.

Plus, I'm a softie for a FAQ. I don't want the FAQ as a page, and not all in one run-on document, either (that's what the database is for - to let us get individual items, instead of all the stuff in one 'pile'), but tinkering with a simple example-program has always been the best way I've found, to get started.
