Carnivalia, and an open thread

Here are a few carnival announcements, but mainly what I’ve got is announcements of impending carnivals—there’s going to be a bunch coming out next week, I guess.

Discuss the imminent dissolution of the blogosphere into collections of links linking to other collections of links, which will lead either to irrelevance and destruction, or reach a critical level of self-reference that will generate consciousness as an emergent property. Or whatever else you feel like.
