Make more of your pages dependent on JS, and you'll be able to
get that statistic even smaller. Does that tell you something?

Search engine indexers generally don't run JS. So any content that's
only accessible by means of JS won't be considered for indexing.
OTOH there's millions of pages (depending on exactly how I set the
search term) which are indexed for haranguing the indexing robot that
its browser doesn't support javascript. I wouldn't want to waste my
search engine credits on that sort of administrivia.
JS has its proper place, for optional extras, I'm not saying it
shouldn't be used: what I /am/ saying is that in general it's a
mistake to make a page or site dependent on it. The last time I
checked a JS FAQ, it said pretty much the same thing.
