I missed this.
The bluster.
What Jimbo said: he is that foolish. My guess is not, he'd back down. I don't think he understood what Tango was saying, he may have been thinking of "the community" as being only a core of bigmouth blowhards locally dominant. No, Tango meant the real community, which is so far only lumbering along, distracted, half-asleep. If it wakes up, Jimbo would salute it, or be left in the dust as no longer relevant.
I think his bluster is a sign of loneliness. Only the real community, awakened, "the sum of human knowledge," as an active entity, could realize the wiki vision. So, here, he is challenging it, poking it. Trolling, in fact. It didn't even notice.
