My worry with this is that it snowballs the hivemind effect.
If downvotes reduce visibility and Twitter is composed of 60% A's and 40% B's, I will expect to see vastly more A content than B content, since the like-to-dislike ratios will differ by a factor of more than 2 (over twice as much A content).
In my mind, Reddit is a prime demonstration that voting to say "I find this content objectionable" and voting to say "I disagree with this content" are often indistinguishable.
