The Madness of Crowds and an Internet Delusion
This article surprised me for actually using the term "hive mind" to refer to these new content aggregating sites like Wikipedia and YouTube. It is probably worth noting that in the past there were several hundred newspapers which were independently owned and while they all used the AP for some information, most still sent their own reporters to local and regional events. Now there are only a few reporters covering more regional events and all the information is funneled in databases owned by a handful of companies. There is a valid argument here I think that the lack of diversity in the field of information management is a detriment to a culture which has traditionally grown by low barriers to entry existing fields.
