Via Don Park:

"... I propose that, while people appear intelligent and have complex behaviors individually, people get dumber and their behavior simpler as group gets larger. If this is true, then given a large enough group of people, group behavior will be indistinguishable from the behavior of a buffalo herd. ...
...With buffalos, only female buffalos can reproduce and once a year. With bloggers, every blogger can reproduce year round without any limits to the number of offsprings. We are worse than rats or rabbits. We are worse than SARS. We are the Borgs."

The buffalo analogy does not fit very well -- who would like to be compared already gladly with a buffalo? There are mainstream topics discussed in the blogspace that are comparable to the phenomena of the mass hysteria (which fits to the buffalo herd). This forms the larger groups or communities of blogs in the space often reflected by their blogrolls. But the discussions are often controvers and not all of them are of the same opinion about the direction to go. So also the Borg analogy does not fit: the only community is blogging where assimilation can take place. BTW the term is already in use and a known as B0rg
