Lol! I have noticed that it can be dead at times. I sometimes use the 2x promote option, where your post is prioritized to show up, but costs you twice the upvote. I just see it mainly as an experiment. I've gotten a couple of dolphin votes from it.

When did you start using it? Make sure your balance is above zero, or your posts won't show up at all, and your life would truly be zero percent differenter!
