The Reasoner sounds like it could be an interesting online magazine:
The Reasoner is a monthly digest highlighting exciting new research on reasoning and interesting new arguments. It is interdisciplinary, covering research in, e.g., philosophy, logic, AI, statistics, cognitive science, law, psychology, mathematics and the sciences.
The first issue contains a discussion of logical truth based around the example of Lois Lane kissing Clark Kent / Superman. I like it already.
