This is something I still don't understand. It's supposed to be a way to tell someone you like their post. But you can't do this to the same person twice without doing it to others. So you have to do it people who's posts you don't necessarily like to do it to those you do. If you do it too little no one can do it to you, if you do it too much you have to stop for a day. People consider these a status symbol but you can buy this status at the status store. If this is making any sense to you you're way ahead of me. lol
