For the first time, Facebook is letting users edit their posts after the fact. The change will be available to some people on the web and the Android mobile app later in the day on Thursday; an iOS version is supposed to follow soon after. Like many of Facebook’s new features, this is a gradual rollout, so don’t be surprised if it doesn’t appear right away. When it does show up, the feature will let users click to edit a post, then preserve a viewable history of the changes, hopefully keeping users honest enough to use it mostly for typos and bad grammar. Facebook first introduced comment editing (also with an edit history tool) in mid-2012, but it’s so far held off on letting people actually edit posts. Until now, that meant you had to outright delete a post to correct something misspelled or poorly phrased, wiping away any comments and likes.
