Good post, though I thought that it is a little too focused on money.

The problem on Less Wrong is that there exists an unidentified subgroup who believes that 1.) the best you can do is support the SIAI 2.) most people can best support the SIAI by donating money. This view might not be the general consensus here, yet the most influential people certainly believe so.

What is necessary is a paper or article sequence that outlines a decision procedure and exemplifies rational choice by dissolving the question about the best (most effective) possible action(s) one can take to benefit humanity and possible help saving the world. This hasn't been done. Supposedly you should be able to conclude an answer here by reading the sequences. That might be the case but isn't very effective as it is at best treated as an marginal issue. How to save the world is not an explicit conclusion of the current sequences.
