Fair enough about karma. But first sentence of Konkvistador's post (after the rhetorical question) says:
we very seldom seem to adopt useful vocabulary or arguments or information from outside of LessWrong.
And the second paragraph of the post begins:
The community seems to not update on ideas and concepts that didn't originate here.
That looks a lot like saying, "LW is not working on non-LW material enough"
Well, look through the examples, or heck, posts since then. Do you see people refusing to update? 'No, I refuse to believe the Greeks could have good empirical grounds for rejecting heliocentrism! I defy your data! And ditto for the possibility Glenn Beck wrote anything flattering to our beliefs!'
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
