Ask HN: A delete button for the web.

I go to many websites, some of these sites I go to daily and I have to re-scan the same content for new information, its frustrating. My email client has a delete button, I just push the delete button once I've finished reading and its gone. I want the same thing for websites, like a buffer button, click it and I will never see that article link again. If I'm searching real estate, once I've checked a property I want to be able to press a delete button and not see that content again. Maybe websites could hook into this data and serve me new content. Maybe my workflow is just plain wrong.
