While your idea is interesting, I don't want it implemented on Perlmonks as long as any user can put Javascript on pages that get seen by other users.
Maybe it's just me, but what does one have to do with the other? Obviously the any user putting javascript is a security flaw and should be fixed, but how does that affect perlmonks displaying javascript to enhance the functionality of the site?
