The Journal of Spurious Correlations has a relationship with The Standing Group on Political Methodology.
The former says its mission is “is to provide a legitimate venue for exploring pure and applied methodological questions in the social sciences in the company of colleagues without fear of professional embarrassment or reprisal.”
The latter sponsors a fun workshp called “Methodology Matters.” [NOTE: The link is to a large PDF file.]
This is more about theoretical methodology than about applied methodology.
