Patience is the answer. I didn't get 5 hearts and a piece of heart just by posting good posts. People won't notice you just because, and if you're funny they may not laugh. I learned that to get even one more heart container, you just need to be patient and post good posts. I know a couple of people are attracted to long posts with excellent grammar but if you don't think you can do that, well just post friendly and happily. : D
