The functional solution to this issue at the moment is having several people see the horoscope on the same day - if three people are watching the feed, and one votes 'unhelpful' and the other two vote 'sort of helpful', the horoscope stays in the active pool, even if the 'unhelpful' vote comes in first. It does give whoever votes on a horoscope the first time it comes up an unusual amount of influence, but hopefully it'll be balanced enough for horoscopes to stick around long enough for a few rounds of voting.
