I like the simplification of the cards and as you know, I am really hoping that people start using the rating system heavily to test out future capabilities. I wonder if it would help (or be annoying) to have a tiny little popup reminder near the stars so when they scroll toward the end that it says something like:

"Would you like to rate this post
It would really help our testing"

Thanks for the mentions and inclusion in the post. Keep up the good work.
