The recent history carnivals have been setting somewhat arbitrary limits on the number of posts to be included (and announcing the limits on publication, not, as near as I can tell, when the call for links is sent). I like the carnival, but I wonder if that is the way to handle it? If the self-nominations are really coming in by the score, it might make sense, but then the Carnival does lose a bit of the "drawing the community together" function it would play if it cast a wider net.
To be fair, this is a very good edition of the carnival: well-displayed (quite stylish, actually, as you'd expect from someone of Natalie Bennett's talents and taste) and well-explicated and organized. Great stuff, from Hobbits and Carribbean Carnivals to sheep's eyes and bull testicles. Great stuff!
