CT Blogs

I've been journeying around the Web to see some sites billed as "critical thinking blogs." So far, most fall into these classes:

Skeptic/debunkers

People promoting college logic courses, Truth Tables and Venn diagrams
New Atheists
Ideologies defending themselves. Naturally they assume critical thinking is on their side and it is the other guy who doesn't use it.
Those actually talking about CT as it is most generally understood

People know that we need more critical thinking but part of the problem is that many of us are not sure what it IS.
So probably the first item on the agenda is to attempt to define critical thinking. (Anyone like to do a guest post on that?)
