If you’re coming from MetaFilter, or more specifically, MetaTalk, my main site, Celtic Studies Resources, emphasizes Celtic medieval studies. But there are a number of more general links on things medieval there, in the Resources section. There are also some good meta sites on things medieval. Labryinth is one. Orb is another. I’m rather fond of Websites Medievalists Should Know. There are a few others listed in my bio.
