If the urge, desire and instinct to communicate is universal, but only the means of production have been democratized since the advent of blogging, then I wonder: fifty years ago, what were the people who are most likely to be blogging today doing to express themselves?

I suspect that they were much more locally focused. Writing letters to the editor (because people still read the paper), aligning with community social organizations, being more actively involved in their communities.

So now we're able to form narrowcast tribes across geographic (and even temporal) boundaries. Are we better off? En masse, such connections may leave whole societies better off (Arab spring) but I think that perhaps we won't realize the full benefits until the focus returns to the local. And that won't happen until there's a rise in the locality of the internet.

Think reinvention of the local paper; or maybe a craigslist for the issues of the day.

And that can't happen until the technology is in the hands and power of EVERYONE. Think Kindles (or iPads, or whatever) in a rack at your McDonalds, literally replacing the local paper. Perhaps the biggest advancement here is the price point; but we need to cut that iPad cost in half perhaps 5-8 more times for this access to happen.

When that day hits--the day of the ubiquitous $1 Kindle--then I think we can claim democratization, and we will see a return to locality and the strengthening of our communities.

But my point is that if tablets, which people refer to as "post-PC" devices, in some significant measure replace PCs, then they only have consumption devices.

One reason for the popularity of these devices is that people are producing more content. Folks aren't watching CNN/BBC on an iPad but self produced Youtube videos and they're reading more than NY times bestsellers on a Kindle.

There is an assumption here that people with a PC will automatically become producers which I think is wrong. For people to become producers they need incentive and opportunity. These devices and the ease of content creation is means the opportunity bar is much lower (e.g. you don't need to get a publisher to agree on a manuscript to publish); and the incentive is higher (you can monetize content you produce whether its apps, books or videos much more easily).

But, if you spend much time on YouTube, it is surprising the range of people who have become content producers. To give just one example, my wife is fascinated by all the people doing makeup tutorials. These are people who might have explained things to a few friends, maybe, and now they have audiences of hundreds or thousands. Most of them are made with webcams on their laptops, and there is no reason they couldn't do the same thing on iPads or iPod Touches.

But post-PC devices are only partially replacing the PC - in those areas where they're better than PCs. We're not losing anything, only gaining something new.

How is it consumption when someone e.g., records a song in GarageBand?
