Text before editing was “The Hokey-Kokey is getting rather boring at this point; do people have any other ideas for dances they’d like to do? We probably need to plan such dances in advance; come onto IRC and vote for which sort of dance you’d like, and I’ll try to come up with a plan in comments to this post.” The edit was legal due to a weird interaction of the dynastic and core rules, in which an official post (such as a dance post, like this was before editing, and still is) can be edited into another sort of official vote; and due to another part of the dynastic rule, it was “Open” - for voting (see the text!) - all this time! So it’s timed out now; you could have voted for it over the past 48 hours, but nobody bothered even to comment, making editing legally possible (strangely, the rules for editing official posts like dances and proposals are looser than the rules for editing unofficial posts…)
