Tales and Chronicles
Jewel of the North, formerly know as vincegetorix
Nentir's Vale by Mike Mearl? I dont know if the Vale was worked on by a particular author, but Mearl's the one who talked about it the most in the past year and I loved what he did with some 4e supplement like Hammerfast (re-read it yesterday, really original take on the classic dwarf hold).
