I'm becoming used to the new system. The posts that are "highest rated", however, frequently have far more negative reactions than positive. This stems, I think, from your question "Is this a good post?" instead of "Do you agree with this post?". Before I read your FAQ on the rating system I clicked yes if I thought the poster had made a good argument, whether I agreed with it or not. Many readers may be doing the same, elevating well-argued posts roundly rejected by the majority of readers to "highest rated status"
There are far fewer trolls now. They are too lazy to make the effort to rate other posts. That is a good thing.
