Most users on the web spend most of their time in apps. The most popular of those apps, like Facebook, Twitter, Gmail, Tumblr and others, are primarily focused on a single, simple stream that offers a river of news which users can easily scroll through, skim over, and click on to read in more depth.
Most media companies on the web spend all of their effort putting content into content management systems which publish pages. These pages work essentially the same way that pages have worked since the beginning of the web, with a single article or post living at a particular address, and then tons of navigation and cruft (and, usually, advertisements) surrounding that article.
Users have decided they want streams, but most media companies are insisting on publishing more and more pages. And the systems which publish the web are designed to keep making pages, not to make customized streams.
It's time to stop publishing web pages.
