Well is there anywhere that focuses on say history of science issues? Even if people don't get a heavy dose of Bayesianism they can still get a pretty decent background if they get the basic ideas of Popper, Quine and Lakatos for example. And it isn't like LW really does focus on philosophy in the general sense.

I suspect that more people would benefit not from emphasis on philosophy but on clear thinking. If that's what we focus on a lot of the general skeptical websites can teach simply by osmosis a lot of the basic good habits. (Yes, I know that's a claim that a lot of people here seem to disagree with. Part of the issue is that the aims of the skeptical movement are not identical to those of the rationalists).
