Here are the two reasons why the 12 hour payout time is the best thing to happen to Steem:
1 You get paid SOONER!
Do you remember the dark ages (yesterday) when you had to wait a day or sometimes a day and a half to get paid? That was brutal! Now the posts you made last night are getting paid out this afternoon.
2 The trending page has much more movement.
Back int he dark ages the very popular post would be at the top of trending page for up to two days. Now we get move movement and more exposure to new posts!
This great for people like me who have short attention spans and are not the most patient. The 12 hour payout time was the best change so far!
