However, I think that good perception of the flow of the grid is key here. If the grid has been motionless for a few days, then clearly one persons investment in what happens to it is decreased, so maybe a gridhog is in order to kickstart things.

However if you have a few days of intense collaboration where people are spending significant time on individual squares and then the gridhog comes in and blows all that work away, you are going to get a backlash.

TCA still "wins" for best analogy of Gridcosm being akin to a garage band: a bunch of folks get together and jam out for the fun of it, people play off each other. The gridhog picks up the guitar and takes the spotlight, playing powerchords for 10 minutes while the rest of the band sits on the side.

Now, if your argument is that the definition of collaboration should include multi-levels, that's cool, noones trying to deny your revolutionary stance, man. But even "evolutionaries" like Duchamp and Cage were respectful of their peers and respectful of collaboration . . .
