I just found out you shouldn't do that... I'm still pretty new to steeming, and I been upvoting like it was going out of style! Apparently that's now the best way to earn curation rewards. Which is a shame, cause I was having a blast. I felt like Oprah. "You get an upvote! You get an upvote!
There is a great post here that explains what's up, if you're a noob like me, it's pretty informative.
Read that post here:

And make sure your vote matters, but most importantly, get out there and steem!
