Honestly, I think other reddit alternatives could benefit from adding something like the labels from Tildes (exemplary, off-topic, joke, noise, malice) in order to create sorting algorithms for different types of users/communities.
It could, for example, allow people who are tired of the constant jokes to have comments which get labeled as jokes sorted lower, which could even be the default in communities intended for serious discussion... or you could do the opposite and sort funny comments to the top when jokes are the purpose.
