This got linked to on facebook, and Rob Bensinger made the following comment:

I included most of these in my list, but I wouldn't include The Virtue of Silence, Biodeterminist's Guide to Parenting, Burdens, Nobody is Perfect, Toxoplasma OF Rage, Chronicles of Wasted Time, The Categories Were Made for Man, Radicalizing the Romanceless, Living by the Sword, Meditations 1-3, Untitled, Social Justice and Words Words Words, Fetal Attraction, I Do Not Understand Rape Culture, Unspoken Ground Assumptions, Should You Reverse Any Advice You Hear?, Joint Over- and Under-Diagnosis, What Human Universal Experiences Are You Missing Without Realizing It?, Phatic and Anti-Inductive, Beware Isolated Demands for Rigor, Giving and Accepting Apologies, The Courtier's Reply and the Myers Shuffle, My Id on Defensiveness, The Zombie Preacher of Somerset, Rational Home-Buying, Apologia pro Vita Sua, Money Money Everywhere, Fish (Now By Prescription), An Iron Curtain Has Descended Upon Psychopharmacology, Schizophrenia and Geomagnetic Storms, And I Show You How Deep the Rabbit Hole Goes, Five Years and One Week of LessWrong, Highlights From My Notes From Another Psychiatry Conference. And I included many that were left out. A few of these I think are unusually bad posts, but most just don't seem essential for people getting started on his writing (or their points are made better elsewhere), though there are lots of fun/interesting bits in them for the completionists.

Might consider Parable of the Talents and Epistemic Learned Helplessness. I haven't read Why I Defend Scoundrels, Mitt Romney, Non-Conformism, Offense versus Harm Minimization, or Towards a Theory of Drama, Straw Individual, Revenge as a Charitable Act, Hope! Change!, Approving Reinforces Low-Effort Behaviors, What's in a Name, Why Support the Underdog?, That Other Kind of Status, A Parable on Obsolete Ideologies, Bogus Pipeline, I Appreciate the Situation.

Stingray suggested that a condensed list would be useful, and judging by the 6 upvotes several other people agree. In order to do this, I've taken the intersection of the two lists (by removing the items that didn't make Rob Bensinger's list from the OP list). I'd expect what's left to be higher value pieces. (although a few removed items definitely sound interesting.)
