This is a very interesting thought process. Tumblr and 4chan in my mind are extreme examples of the unsterilised Internet you refer to....

For the last year or so I've decided to avoid news outlets as much as possible. So I've updated my Reddit subscriptions to remove anything that might be a news channel, I no longer frequent the BBC news website, and avoid newspapers and TV news as best I can.

The constant fear mongering and general bad news is at times overwhelming but oftentimes just unnecessarily miserable (IMO). It's like being given a long list of problems you can't do anything about. So I've decided to simply switch it off.

I would much prefer your approach where my news could somehow be "sterilised", taking out anything that is overtly negative leaving only factual stories (e.g. business, technology and so on).
