Yes - I am trying a few different strategies. At the moment I am trying to upvote between 15 minutes and 30 minutes on posts that I know will make over $100. The only problem is sometimes these posts end up with 500 upvotes so the Curation reward is divided between 500 people. I have tried a few other strategies (Voting in 1st 10 minutes, Voting after 30 minutes) and and all I ever make is about .001 SP for my upvotes. I am working to get my Steem Power back to 100 % so that I can see how I do when I only Vote at 100 %. I do much better as an Author than I do as a Curator. I also tried Resteeming several very good posts and made zero SP from that strategy.
