 <p>There are only 100 web sites that are in the list of top 100 websites, and they count for only a measly percentage of all websites. A fabulous percentage of websites are rarely visited. Because they have few users, the receive little testing and even less complaint from users that need it to work without javascript, or with a version different from what the developer happened to use. </p> <p>Maybe the worst part of it is these sites make use of all sorts of showy bling in the form of Javascript and flash to look interesting or important.</p> <p>Core functionality in these cases is really just basic site navigation. </p>
