@Christina Warren -It’ll be interesting to know what happened in the dev process that caused the scope to change so widely and for features to be pushed back to the future.

The blackout thus far seems inauspicious for meaningful forensics.

It was a serious issue that needed radical action, which has already been costly.

There are weighty commercial considerations, and standing within the industry at stake.

Who was the Post Formats UI in core really for? WordPress bloggers and theme-retailers? Hmm.

When something like this happens, the analysis & explanation is likely to be foregone in favor of fostering the restoration of morale & team-cohesion. People at the heart of WordPress are devastated. Mistakes or misjudgments probably happened ... and rather than "accounting", WP now needs everyone who may have been involved, doing their best work on the recovery effort .... the involved folks probably among the finest & most-crucial on the team.
