If it were more detailed so you could communicate more like insightful, interesting, sad, funny, then maybe people would be able to vote up and curate in more creative and diversified ways.
Yes, I like where you are going with this..... we could have more than one way to vote and reward voters who voted as most people did, for example if your bot voted "funny" but most people voted "angry" then your bots gets nothing and its fair since you didn´t actually read the post.
