I've actually been debating what to do 'bout that problem on both sides of the coin. I want my content to be noticed, but I also want to try to upvote new, high-quality users with my near-valueless upvote, while ignoring the junk.

So far the best I've come up with is to mute those low-quality posters (so,so time-consuming!), look around for good ones, and on my own end just persevere - I know I'm trying, doing my best with what I have, and that has to be enough to satisfy me.
