I think there's a notable point here that has not been covered.

It's not just bronco vs. sturgeon, 
it's bots vs. no bots. 

Repeatedly in the past few months I sat on continuum and watched a 
person log on, chat with me for five minutes, and log off. Then a few
minutes later someone else would come along. Without bots, critical
mass never got reached. Meanwhile, you could log onto sturgeon and
have t. 

I have no idea how much of the preference for sturgeon is people
who like twinky upgrades vs. people who just want to be in t-mode.
