On a related note to the post below, I think that, due to the community aspects of blogging, it would be possible to write a piece of software that generated conversations that could occur between various bloggers when they meet and talk. Not that bloggers as a group are limited in topics of discussion, but that, knowing a particular blogger, and their daily surf lists it is possible to figure out both their general interests are and what their inputs have been over the last few days. You could use a pattern algorithm to then match the inputs and interests between the group, and probably accurately predict what the topics of conversation would be. This comes from having the sorts of conversations that I expected to have with Todd and Nathan.
