There is a new critical rationalism blog. I wrote a post for it about liberalism.
I updated Fallible Ideas to work well on iPhone and iPod Touch.
EDIT: I am not associated with the CR blog because the owner misquoted me and refused to change it.
The good thing about the CR blog is the resources attached which are carried over from Matt Dioguardi's now defunct Critical Rationalism website.
Not to be missed!
See also this list of CR resources that I am bringing up to date at present.
One of the 2010 additions is the fallible ideas site.
