@leeloo The idea of boosting your own post or reply is to make it more visible to people in different timezones, or to highlight it days/weeks/months later.Because the main Home timeline is chronological, posts tend to be seen in countries that are awake at that point. So, you might boost a post/reply e.g. 12 hours later to reach people in different countries.If a reply has particularly useful info, you might boost it for the same reasons as a post.
