Other fanblogs and fansites
There aren't a whole lot of sites I've seen dedicated to Pathologic, but whenever I do track some down I will put them here!
Pathologistics [archive] - A neat little blog where two guys talk about their experiences playing the original 2005 release of Pathologic. I haven't read through every post (yet) but they're written in a very fun style. They only talk about the Bachelor and Haruspex routes, but apparently there used to be a separate blog for the Changeling (or Devotress) route that is now defunct. If anyone has an archive to that, then please let me know!
Pathologic the Musical - A blog dedicated to a musical version of Pathologic that one of my friends have been working on. The songs they have written for it are great, go give their work a peek :^)
