I believe Eliezer's goal was to keep people from thinking seriously about the topic, from that point of view the current strategy appears to be working just fine.

There's not been much discussion here, but it's been discussed in a number of other areas, to such an extent that there are 1 RB search result to every 9 TDT search result. From a cursory examination, a significant amount seems serious enough to involve deep enough discussion of the topic to cause either evilSuperintelligence issues or possible psychological harm.

It could have been more prominent, of course, but I'm not convinced that it didn't reach greater levels of discussion because of Yudkowsky's response.
