Thanks for your effort with this video post MarketingMonk :-)
Nevertheless, I would like to add that one should not expect to earn decent amount by curating content. What people (especially the majority of users who don't have large amount of SP) should expect is something around 0,001 steempower which is quite useless. Which means that it is fairly impossible to get steempower through this way.
It is better to forget about the money while upvoting and simply curate stuffs that you enjoy reading or think that they deserve to be upvoted.
