They redid their UI last year to be more Web 2.0, which would've still been a mistake, if a less grave one, had it been competently executed.
I wonder if it's still serving a complete list of article names to every visitor? If so, that all by itself is probably a big chunk of that 691K.

?!? What is going on there?
