Animals made the drop-down! (Yes, I know it was probably there forever but I never notice these things)

Can we play "Shameless Speculation" again? It's a lot of fun. What do you think the third blog will be? What else is science-y and is broad enough a category that it could feasibly contain itself? We have Space, we have Animals... maybe Medicine? Do you think we'll know the new Recruit or will io9 go outside again?
