Yes, discusing it, that is indeed what we are doing

Every one wants to see the world in their own light, why not let them. It's a big enough world to let shiney happy adventures rest beside the Grim and gritty ones. Give the DM's a large amout of artistic freedom, but have them run their possible adventure ideas by Judges who would hopefully catch any contridictions
I agree. While setting a general tone, there should be plenty of places where the GMs can go. If a GM wants to run an espionage style game, why not if the Heroes are willing and able. If the GM wants to run more of a combat brawler game, again, why not? Perhaps there's some coruption in the League system that needs removal that has only reciently become apparent, or perhaps Dr Eyegore is sending out mind control through the TV. Assuming it can be approved by a panel of judges as a valid adventure (similar to the LEW system), the GM should be allowed to run it, and present the world how he wishes in general context.
What needs to happen is that limits should be set as to how far an adventure can go as to changing the world. Can leadership of a country change? How big a Country? What about Wars? What about destruction of landmarks/Buildings?
What needs to happen also is that events need to be recorded into public history that happen in Adventures, which I would suggest should fall on the players a bit more than the GM (For occasionaly, the players miss something significant, which tends to mean others might have as well). So the history and the world is built with adventures, and as it grows, GMs either have more material to work with that they don't need to make up, or they can simply do something new and simply know what not to conflict with.
But, this should be a fairly open system. Other than the diverging event, everything should be flexable to allow for maximum use by GMs and Players alike, so beyond a bit of world history of how the league came into formation, there shouldn't be much to the world differing from modern times.
Once we set up a few Judges to monitor things (Approval Judges, Adventure Judges, Character Approval Judges, and perhaps Site Judges, some filling more than one capacity) and decide on a basic starting point, we can continue forming the world from there through adventures and proposals.
How they shape the world:
Adventures: These are events, but things that are needed to facilitate this are also created. Villians, other Heroes, non-super personalities, locations, corperations, etc. Once an adventure is over, most of these are open game to be used again, though I encourage the allowing of a GM to hold some control over his own created supervillan for continuity perposes.
Proposals: Changes in the Rules, Options, How things opperate in the campaign, or even major backround information/changes. These need to be approved by approval Judges, and while not retroactive unless specified (and deemed appropriate), can help flavor and personalize the world as things advance. Major Influental organizations, Major world changes and such should be proposed here.
Backgrounds: Players shape the world with their backgrounds. They generate organizations, people, events, and places that might otherwise not exist. While anything majorly worldchanging should be offered up for approval, minor things are good, and add flavor. Flavorful backgrounds with interesting material should be encouraged, or perhaps even background that can be developed through adventures or in adventures (such as unnamed secret organizations).
