A new way to show what’s most new and most viewed.
On a news website’s home or topic page, stamp each headline with a relative time stamp showing how long ago was it published and also how many people already viewed it.
Many web pages exist that are today’s equivalent of “yellow” newspapers. They are not very particular about what they publish as long as they get the clicks.
These websites rely on user behavior, so let’s make them change by obscuring their metrics. Create an army of participating users that “behave” in counter-intuitive ways to confuse these websites. By commenting and liking and visiting all kinds of pages on these sites, if done in sufficient numbers, will obscure the accurate view of user behavior from the publisher. These should be centrally coordinated and seem totally random.
