This echoes some of the thoughts I've been having, that the evolution of posts that we had on Tumblr (where they start at anteaters, progress through biologists, meander into sloth farts, march past geological formations and wind up at Steve's nipples) is something that's really better placed to happen in comments on DW, rather than the 'reblogging by taking chunks of a post and adding onto it' method.

Then we can reblog, ie link to, the comment threads and marvel at the wonder of conversational evolution :D
