Days 1 and 2 of DSM have come and gone, although upvoting for them still continues. This happens to be the DSM post for today, Day 3.
This is how it works.
Every day until steemit no longer exists, we'll be having a DSM post where every upvoter earns from it.
100% of the payout from this post goes to all who upvote it,and everyone gets an equal share once it has been claimed. This is one way whales can help minnows and newbies as their votes will increase the amount everyone is entitled to.
In addition to taking a cut of the payout, upvoting early guarantees you curation earnings.
