From a UX perspective, “applause” needs some work. I had no idea you could click it more than once. The floating +1 is a nice touch, but maybe they could slowly fade the filled-in animation out, so that it’s clear that you’ve clicked it once, but that it is clickable again. And maybe the hand could slowly fill in, with a cap on number of claps? Like 10? Otherwise it feels like I’m vote-stuffing a post.
