Nice to meet you Old-fashioned, call me Brisket. I zap what I value & what I want to see more of. I do this for my own selfish reasons. I'm not some retard that believes I should be altruistic. If I don't zap a note, then I really don't value it significantly. If I bookmark, download, copy or boost then it's probably significant content to me. I should signal that I value that so that I can receive more of it later. What you put out is what you get back.
