Group items tagged

In his 2008 book, Here Comes Everybody, media theorist Clay Shirky suggests a useful hierarchy for sorting through these new social arrangements. Groups of people start off simply sharing and then progress to cooperation, collaboration, and finally collectivism. At each step, the amount of coordination increases. A survey of the online landscape reveals ample evidence of this phenomenon.

Second, other users benefit from an individual's tags, bookmarks, and so on. And this, in turn, often creates additional value that can come only from the group as a whole. For instance, tagged snapshots of the same scene from different angles can be assembled into a stunning 3-D rendering of the location. (Check out Microsoft's Photosynth.) In a curious way, this proposition exceeds the socialist promise of "from each according to his ability, to each according to his needs" because it betters what you contribute and delivers more than you need.

Instead of money, the peer producers who create the stuff gain credit, status, reputation, enjoyment, satisfaction, and experience.

It’s not hard to imagine a slew of commercial applications for this technology. You could compare prices of a product online, learn how to operate that old water heater whose manual you have lost or find out about the environmental record of a certain brand of tuna. But Goggles and similar products could also tell the history of a building, help travelers get around in a foreign country or even help blind people navigate their surroundings.

But recognizing images at what techies call “scale,” meaning thousands or even millions of images, is hugely difficult, partly because it requires enormous computing power. It turns out that Google, with its collection of massive data centers, has just that.

The openness of Wikipedia is instructive in another way: by clicking on tabs that appear on every page, a user can easily review the history of any article as well as contributors’ ongoing discussion of and sometimes fierce debates around its content, which offer useful insights into the practices and standards of the community that is responsible for creating that entry in Wikipedia. (In some cases, Wikipedia articles start with initial contributions by passionate amateurs, followed by contributions from professional scholars/researchers who weigh in on the “final” versions. Here is where the contested part of the material becomes most usefully evident.) In this open environment, both the content and the process by which it is created are equally visible, thereby enabling a new kind of critical reading—almost a new form of literacy—that invites the reader to join in the consideration of what information is reliable and/or important.

viewing learning as the process of joining a community of practice reverses this pattern and allows new students to engage in “learning to be” even as they are mastering the content of a field. This encourages the practice of what John Dewey called “productive inquiry”—that is, the process of seeking the knowledge when it is needed in order to carry out a particular situated task.

If you want to know why newspapers are in such trouble, the most salient fact is this: Printing presses are terrifically expensive to set up and to run. This bit of economics, normal since Gutenberg, limits competition while creating positive returns to scale for the press owner, a happy pair of economic effects that feed on each other.

The expense of printing created an environment where Wal-Mart was willing to subsidize the Baghdad bureau.

This is one of the great conundra of our era: the spectre that haunts every executive, every government, every powerful person who owes her stature to her command of an empire that enjoys its pride of place thanks to the prohibitive cost of replicating it.But lurking in those 80 percent replacements are an infinitude of ideas too weird and too funky and implausible to try at full price. Lurking there are ideas as weird and dumb as a company called (I kid you not) Google, an encyclopedia that everyone can write, a wireless network standard based on open spectrum that anyone is allowed to use, without central planning.
