Why all the karma bashing? Yes, absolutely, people will upvote or downvote for political reasons and be heavily influenced by the name behind the post/​comment. All the time. But as far as I can tell, politics is a problem with any evaluation system whatsoever, and karma does remarkably well. In my experience, post and comment scores are strongly correlated with how useful I find them, how much they contribute to my experience of the discussion. And the list of top contributors is full of people who have written posts that I have saved forever, that in many cases irreversibly impacted my thinking. The fact that EY is sometimes deservingly downvoted is a case in point. The abuse described in the original post is unfortunate, but overall the LessWrong system does a difficult job incredibly well.
