particularly if you're looking at old entries and their comments (and I have no idea why that makes a difference), it's because my lovely domain registrar hasn't completely propagated my DNS changes from last night (in particular, the changes have not replicated across both of my domain's nameservers). Hopefully this will finish up sometime during the next 24 hours or so.
I had pointed fuzzycurmudgeon.com to imwithfred.com during my month-long hiatus, and that's why you're getting redirected over there. But please feel free to visit Fred Thompson's web site on your own time.
