I have never down-voted any one,but when the time comes i will do it.
The reasons you gave for down-voting is what i will base before i spoil someone's day!
I actually see many authors here who earn from curation rewards mostly.
They rarely make posts,but keep looking for great content to upvote.
This rewards are handsome on authors with a high Steem Power and not us newbies.
Thanks for this well documented article of curation rewards,stay blessed.
It doesn't surprise me that many people earn mostly from curation. For me personally, I find it easy to comment or vote for the same reason that it's really easy for me to ask questions in class or engage people in conversation. However when it comes time to actually create stuff, I have no idea what to write.
