Except for the Router Workshop I've never seen another site or magazine devoted entirely to routers. This site is heavily focused on routers but not totally devoted to them. While the router is the most versatile woodworking tool, it is hard to make much with nothing but a router which is why general woodworking mags are just fine, in my opinion. If you look at the articles in them, most of the projects involve the use of a router at some point and that's the way my own projects work. I like Fine Woodworking but I've seen others recommended.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
