@Rob Lawrence -Everything is a post. Why [do/would post sub-elements] need to have a format?!Good characterization of post-structures & their costs ... and the irritation that added complexity & additional (forced) choices can cause. For some users (er, 97%?), the answer may well be, Blow formats; just lemme make a post, will ya?

New, extended, fancier data structures for posts (etc) should not require those who don't savvy document data-elements to 'go back to school', in order to make a 'simple' post. And it would be a big surprise (and brain-dead boo-boo) if WordPress does 'stick it their face'; force casual users to jump through a bunch of computer-science hoops, in order to get a post up.

@Chuck Reynolds -sigh. ... more control for devs.

Like that ol' time flash of irritation shown by Rob Lawrence, the dismissive, superioristic [oh dearie me] sigh of Chuck Reynolds is a natural, innate human reaction. In personal settings, it cuts to the chase in no uncertain terms. If a picture is worth a thousand words, a well-placed sigh can be a whole gallery.

But in public fora? On a website linked to on the Admin page of every WordPress installation out there? This isn't a "personal setting". Remember Al Gore, sighing his way through a Presidential debate? That was a human reaction alright; we understand how it works .... but for a clearly superior person, on camera, in front of the whole country, that was pretty stupid.

It is in the interest of WPTavern, and WordPress more widely, that places like WPTavern be able to happily make a chair for people who will have to be coached through even the most basic quiz on data-structures, etc.

It is a key goal, that there not be a virtual sign on the tavern door: Devs Only! ... and that goal is still a work in progress.
