Why Pierre Omidyar decided to join forces with Glenn Greenwald
   Omidyar believes that if independent, ferocious, 
   investigative journalism isn’t brought to the attention 
   of general audiences it can never have the effect that 
   actually creates a check on power. Therefore the new 
   entity — they have a name but they’re not releasing it, 
   so I will just call it NewCo — will have to serve the    
   interest of all kinds of news consumers. It cannot be a  
   niche product. It will have to cover sports, business, 
   entertainment, technology: everything that users demand.

Can't disagree more with this.  The only reason news outlets currently have to cover all of that stuff is that they're still trying to act like the newspapers and TV/radio stations they replaced.  When you had only one or two newspapers in town, and only two or three TV channels within range of your rabbit ears, the news business was necessarily a general one.  There is no reason at all to impose this model on the Web, and there are a lot of reasons not to.
