EVER noticed how long it takes for web pages to load these days? You click on a link and wait and wait, and then wait some more, for the content to trickle in. If nothing has happened after ten seconds or so, your impatient correspondent hits the browser’s stop button followed by the reload key. In desperation, he sometimes loads the link into a second or even a third browser tab as well, and bombards the website’s server with multiple requests for the page. If that fails, he gives up in disgust and reads a newspaper instead.
