@chandima Favorite can be used like that, but you can also review your favorites. So you could use it like that, like a private tip jar to the author to let them know you liked the toot, or you could use it like Internet Explorer used favorites, like bookmarks. We don't have to all use it the same way. However, do keep in mind that Favoriting is a much more private affair than it was on Twitter. Only you and the author see it.
