I can not resist to quote from the page you mention:
update 2005-09-23: noticed
this fantastic example
of how to avoid all
the
AJAX malarkey to do this trick. I'm surprised I didn't think of it
myself! I'm blinded by science, I suppose - applying new tricks to
everything, when a simple gimmick will do the trick even better. Well
done, Martin!
So this might be just another demonstration for Ajax being the perfect solution for some problem which still needs to be discovered...
