The aggregated "wisdom of the crowd," epitomized by Google and Wikipedia, is rife with opinion, misinformation, and lies because Web 2.0 creates an "environment where anyone can say anything," Keen argued. And that's "a bad thing for the cultural producers, the creative class,"

Web 3.0 is better.

I too don't understand a common hatred against Wikipedia. I'm not all that familiar with how it is maintained, but it is my understanding that it is moderated by the community so that blatantly false information is weeded out.

I like wiki's. Even if the info is false I can often get a grasp of meaning from the entries that leads me to more reliable data. I also like the scifi wiki and all the mini-wikis that are out there.

Exactly! I'm not advocating its the final source of information, but it does provide some good starting points on many things.

I read recently that the frequency of error in Wikipedia was quite similar to the frequency of error in one of the major commercially-produced encyclopedias. It's not like we're competing against perfection.
