| Mar 8, 2012 at 15:32 | comment | added | Fernando Muro | Jacob, Tom, your arguments also show that the homotopy category of 1-connected spaces cannot be enhanced to a right pointed derivator. I just wanted to point this out in case somebody finds it interesting. | |

I realized also that, more simply, you can just write down a diagram of simply connected spaces whose usual holim is not simply-connected, apply the hypothetical $F$ and $G$ to it, and get a contradiction. | |
