That would be a pity -personally I think downvotes, for all they can be abused, are a necessary counterpart to upvotes if you’re going to have a voting system at all. “All attention is good attention” doesn’t work well in real life or online.

Now if a change was made to allow individual magazines to choose upvotes+downvotes, only upvotes or none at all, I think there’s a better case for that - let people try different systems for different circumstances,
