Yeah, I still screw up now and then, (not to mention my mouse behaves erratically sometimes) but there's ALWAYS value in showing support to someone for creating something you value.
Besides, every bit of STEEM I have collected is a gift- some of it is from me consciously parlaying the rewards, but it's all still a magical gift manifesting out of communal good will. I refuse to forget that, even when I space out and don't listen to new music submissions or post new material everyday.
