I just found about about Phlox, a (relatively) new weblog in philosophy of logic, language and metaphysics. It's attached to a project at Humboldt University in Berlin. As well as following the tradition of philosophy centres with Greek names (this one means "flame", apparently) "Phlox" is a cunning acronym for the group's research interests.
There's several really interesting posts to check out already. Worth heading over!
