Less Wrong ought to be about reasoning, as per Common Interest of Many Causes. Like you (I presume), I would like to see more posts about reasoning and fewer, despite my transhumanist sympathies, about boxed AIs, hypothetical torture scenarios, and the optimality of donating to the Friendly AI cause: focusing our efforts that way is more interesting, more broadly appealing, and ultimately more effective for everyone involved including the SIAI.

And I'd hazard a guess that the SIAI representatives here know that. A lot of people benefit from knowing how to think and act more effectively unqualified, but a site about improving reasoning skills that's also an appendage to the SIAI party line limits its own effectiveness, and therefore its usefulness as a way of sharpening reasoning about AI (and, more cynically, as a source of smart and rational recruits), by being exclusionary. We're doing a fair-to-middling job in that respect; we could definitely be doing a better one, if the above is a fair description of the intended topic according to the people who actually call the shots around here. That's fine, and it does deserve further discussion.

But the topic of rationality isn't at all well served by flogging criticisms of the SIAI viewpoint that have nothing to do with rationality, especially when they're brought up out of the context of an existing SIAI discussion. Doing so might diminish perceived or actual groupthink re: galactic civilizations and your money, but it still lowers the signal-to-noise ratio, for the simple reason that the appealing qualities of this site are utterly indifferent to the pros and cons of dedicating your money to the Friendly AI cause except insofar as it serves as a case study in rational charity. Granted, there are signaling effects that might counter or overwhelm its usefulness as a case study, but the impression I get from talking to outsiders is that those are far from the most obvious or destructive signaling problems that the community exhibits.

Bottom line, I view the friendly AI topic as something between a historical quirk and a pet example among several of the higher-status people here, and I think you should too.
