   John Larkin and Cursitor Doom are frequently wrong. Their addiction to   
   certain sorts of misinformation may make them popular in their social   
   circles, so they aren't necessarily stupid,even if they do post a lot of   
   foolish nonsense

   A trifle ironic, given that Cursitor Doom's response was placed before   
   my explanation of what was going on. It wasn't all that technical, but   
   he still doesn't seem to have read it.
