  You are not alone. I wrote that blog post while sitting on 
  a Humanscale Freedom Saddle Seat stool ($300). I 
  considered getting into it about Aerons, but thought 
  better of it.
  Plenty of folks here dislike them, too, and have the 
  choice of any chair they want us to order.

  I'd love to do that, but our offices are glass-doored, so 
  not sound-proofed, though that's a good idea.

His submissions are both dead as well: http://news.ycombinator.com/submitted?id=richarmstrong

What's happening here?
