I removed the link. I do not think that the list is too arbitrary but will refine it anyway. Many links originate from Less Wrong and other discussions about the subject matter, the comments having been upvoted or praised. Nevertheless I plan to ask people with good expertise in each category to review the links. So please bear with me. If you see something that is useless, let me know too.
Update 2010-10-22 #1
I added a foundations section to the physics category.
I added Ned Hall and L.A. Paul, on what contemporary philosophy thinks about causality and Being an Absolute Skeptic to the Epistemology section.
I added Less Wrong Rationality Quotes (Sorted by points. Created by DanielVarga.) to the Overview (LessWrong) section.
I added GitHub (Social Coding) to the general programming section.
I added The Art of Math to the misc math section.
“The Art of Math” clearly doesn’t belong (as many other things; your list is too arbitrary).
