Yesterday I noticed that I got a curation reward:
I have upvoted one post of 
but also everything you have done on the steemit platform!
If you click on one of the posts you upvoted or blog entries you can see who upvoted and with which power he upvoted. In addition the resulting curation reward.
Thats the overview from my post one week ago. You can see that for example arizonna got nothing but hr1 got 0.184 SBD! Thats a big difference. Also hr1 voted with just 0.63%. Thats very low but got me like 0.3 Steem Dollars at the end!
@hr1 for the upvote!
