As Steve Blank is wont to say, if anything is to happen, you need to "get out of the building". That means interacting with real life politics, not upvoting stories on a niche news site. Unlike upvoting stories, this is actually hard work.
What's the point of visibility for a story anyway? The point is to actual do something that improves the situation. Voting things up seems like "gee, I wish someone would do something about this, maybe if they happen to see it it will happen".
