According to Tech Crunch, Facebook has finally started to roll out the feature to edit your posts after you’ve made a typo or a mistake. They used to allow you to delete the comment within a few minutes after posting, but you couldn’t delete it if you wanted to the next day. You aren’t allowed to edit the original post that started a conversation because that may change the meaning of the whole thing (which Facebook doesn’t allow). The feature will be rolled out in waves, so some people may have to wait.
