With so many options for post rating, I am just skipping them. It would take me about 7 hours to go through the entire lineup to decide what to use. I suggest up, down, and if you really want 2-3 others.
The first three - thumbs up, thumbs down, and agree. Beyond that, no need to look - I already have, and didn't see anything particularly striking, and I even like playing around with them.
