Whenever my rating increases, I receive a message with a description of my rating changes, and it always ends with a huge "share it!" to encourage me to share the good news. I can also find this information on my rating graph and revisit it later.
However, I've noticed that when my rating falls, there is no prompt to share it. But I really enjoy the humorous aspect of sharing ratings, so I'm wondering if there could be a new way to share a lower rating. Or maybe I just haven't discovered the option for sharing a negative rating yet.
