@evan I see the appeal for distributed moderation but am unsure a dislike button could accomplish it. I recall Slashdot (though haven't used it in a long time) had descriptive words that could be "voted' on, which made filtering for certain qualities (e.g. looking for expertise) possible. I fear that a dislike button could lead to "downvoting" stuff without consideration and maybe diminish interaction. Liking adds a positive feeling but I don't want to put effort into disliking people's stuff.
