I remember reading these two tweets:

and thinking that the second one (in response to some people telling him he was factually wrong about pg, and should maybe cool down) in particular marks him as a toxic passive-aggressive douchebag. Do you think these are fine, too?
I didn't know he was head of Django, which I don't use, but wouldn't go as far as assuming his personality leaks out to the project. It may well be that he's doing great things in Django, people often compartmentalize.
