I don't understand the problem with waiting 3 hours as opposed to 30 minutes for an upvote? I don't completely understand all the inter-workings of Steemit, but I know that payouts don't happen until 7 days after you've made a post so unless you send in for the vote with final minutes before payout of your post.. well next time leave more time, but otherwise.. explain what is the big deal from waiting a few hours?
