Twitter is a great (as in terrible) example. I only enable javascript for a few websites so - when I click on a link to twitter - I see the twitter page being rendered and then this is all erased and twitter puts up a screen demanding that that I click on a link to see the content. After this click and a further page load I get to see a few hundred characters (the actual message) and a ton of rubbish, all of which was downloaded and rendered the first time round.
