I look at Steem as: yes, I want to grow my account, but I also want to help other people grow their accounts. So if my vote comes in at 2 minutes or at 6 days and 10 hours - either way lessening any curation I might earn - meh. I'm happy to drop a couple of pennies in someone's jar without gaining a haepenny for myself. And unless your vote is worth LOTS, that's literally the amount of money we're talking about.
