It will be interesting if they are willing to rank things voted by a user's cohort, rather than straight ranking. However, I suspect Twitter's political biases will play an role. Reddit is interesting in that it offers a "sort by controversial" option. Toxic nonsense generally gets downvoted uniformly, while contentious arguments can float to the top.
