I am subscribed to a lot of blogs. They have interesting content, and I'd like to be able to read them. I'm also strapped for time and really should exercise more. Something's got to give.
I'm imagining a device like an mp3 player. Only, instead of mp3s, it's loaded with text. Text that it loaded from my various feeds. I put on the headphones and hit play, and it reads me the news of the world in a synthesized voice. I can keep up to date with information...while jogging, lifting weights, or otherwise occupied.
This would probably be useful to other people too -- citizens of a democracy have to be well informed on current events, or democracy dies. In an increasingly time-strapped world, being able to do two things at once reasonably well is a welcome gift. I'm hoping that this leads to more news consumption than before, but somehow I doubt it.
