Dual Perspectives Article: Collaborative Culture
User-created online culture isn't "mass culture," exactly; no single blog post gets as much exposure as, say, an episode of American Idol. But it's culture by the masses. A Pew Internet & American Life Project poll in 2007 found that 64 percent of American teenagers were posting their own content online while 39 percent of teens were sharing art they had created. #The internet's vast, instantly accessible mountains of individually created text, images and sounds are examples of what economist Nicholas Gruen describes as "emergent public goods" — things that simply amass themselves into existence and serve the public interest. (Sometimes their service is particularly immediate, as when Twitter and Flickr provided real-time reports of last November's terrorist attacks in Mumbai and were picked up by such media gatekeepers as The New York Times.) #There's also a whole new category of "works" that has evolved with blog posts and online photo galleries: public commentary.
Life With Alacrity: The Dunbar Number as a Limit to Group Sizes
for a group to sustain itself at the size of 150, significantly more effort must be spent on the core socialization which is necessary to keep the group functioning. Some organizations will have sufficient incentive to maintain this high level of required socialization. In fact the traditional villages and historical military troop sizes that Dunbar analyzed are probably the best examples of such an incentive, since they were built upon the raw need for survival. However, this is a tremendous amount of effort for a group if it's trying not just to maintain cohesion, but also to get something done.
