RI's blog has been on the fritz lately as Blogger has caught some kind of cold it can't get rid of (I've been having trouble too). His new posts aren't showing up on the main page so he's posting links to new posts in the discussion board.
Here is one of the latest and I highly recommend it. And be sure to read the comments - very interesting stuff. And drop him a line if you think you can fix his blog.
