The secret to getting about 30cts of upvotes on a comment or a post like @slothboarder did, is to use eSteem, the mobile app developed by @good-karma. It doesn't bring these upvotes on every comment, but only once or twice per day, and I also think there is a minimum word count before these upvotes apply. But hey, let me post this via eSteem, and then you can check who upvoted this and compare with the comment here-above.

But then again, what works even better than that, is to just post the best content you can and hope for some whales to come along. That seems to be working out just fine for you :)
