It was an example how embarrassing facts (yes, there was a small error, which didn't change the point though) about the Great Leader are being hidden by the karma system by "Eliezer-follower cultists".

Second, it was a good example of how trolls are being hidden by the karma system.
If you know more Eliezer Yudkowsky facts, post them in the comments.
