What I mean is, my vote is only worth $0.01 at the best of times. I've yet to experience being able to give a bigger vote than that.
I'm pretty curious about the curation reward as well; the whale that's voting on kasia's posts every time - glitterfart - is collecting 300SP per week in curation rewards, but I don't know if they're upvoting more than once per day. If they're only voting once per day, that's a 40 SP reward per post.
I found this tool to calculate the curation reward, it seems like even for kasia's post it's only a few cents https://s3.amazonaws.com/yabapmatt/bottracker/curation_calculator.html
