A. Journalism isn't going to die. Newspapers might, but Newspapers != Journalism B. They don't need hackers, they need entrepreneurs. As cool as hyperlocal news is, it's mostly just an iteration on the newspaper. It's not changing the game in any way.
The only thing I see wrong with newspapers is that the medium doesn't sell advertising very well. It only worked for so long because it had all of the market. Where else would you advertise in the 50's or 60's? I don't buy the "Yesterday's news" argument. I don't think that matters to 99% of the people. If that really mattered, TV would have killed off the Newspaper with CNN. Hell, radio would have killed off the newspaper if it mattered.
