I mostly like no points displayed, but with one exception - comments that provides information you are unsure of trusting or not, and there hasn't been replies to it yet. (eg. scythe's recommendation on domain registrar [1]). In order to have better information on the post's trustworthiness, I had to click on the user's link. I guess we'll need to wait to see how much other nuances for this no points display.
