I'm not a N9 only user but I'd like to see this place to welcome Harmattan developers/users as well. Actually I though they were already welcome since there are sections for those discussions. So I'd also expect them to be presented in the council.
To me it seems that the device generation transition just causes more noise this time around since there are more n900 users than there were 770 or n8x0 users but essentially it's the thing as with the previous transitions. It's Newton's 3rd law of motion - "For every action there is an equal and opposite reaction."
