Infotopia
Cass Sunstein writes
Participants in the blogosphere usually lack an economic incentive. They are not involved in any kind of trade, and most of the time they have little to gain or to lose. If they spread falsehoods, or simply offer their opinion, they do not sacrifice a thing.
I’m not certain I totally agree. Bloggers sacrifice time or attention. They have an opportunity cost and, thus, choose to forgo other opportunities to blog. Most importantly, they forgo making money. I suspect as information increases in accessibility opportunity cost will increase. In other words, individuals will be more selective in what they contribute because there so many other things they could have been doing.
