Tim O'Reilly has a provocative and short piece on the growth and value of short form content. While I agree w/ the growth, and certainly see some value in large numbers of short pieces of data, any insinuation that this is or should be the future for communications in misplaced. To that end, my prediction is that newspapers, magazines, books, broadcasts that really do a great job of doing in-depth coverage will do well. Any issue of The New Yorker will tell you long form is alive and well.
Again, it's easy to get caught in the either/or argument -- either long or short, rich or poor, etc. There is room for both, but the pendulum has swung too far to the short burst - we are due for a backlash.
