The fact that they have Braham Norwick's article on the origins of knitted fabric in there annoys me, because Norwick is well known among textile people to be wrong, wrong, wrong about many things. While medievalists.net does turn up some interesting bits, I don't like them because they seem to just collect stuff and publish what they find without a lot of quality control. (Their web design is also fairly unattractive, though the new template is at least more roomy than the old one and less prone to overflow.)
