This might be more an idea for a player project....
But in light of things like MicklePickle's proposed moving business, things like Glitch National Bank, and other player businesses (yes, even the Lumber Co furor), I wonder how if/how reputation ratings could be implemented--
whether as YetAnotherPlayerProject, or using something in game. Or both.
That way, before entering into a trust-based transaction with a player, someone could see what other's experiences were. Say, before, you ship some goods to someone more conveniently located to a project or a street project. Maybe before teleporting. (I could see an in-game business around teleporting, could anyone else?) Before extending an invite to someone in your posession strewn home. And if we do end up with group housing, perhaps it could be evaluative there. Or before joining a player club that requires you to hand off some primo stuff as a consideration before joining.
The downside of this is that it all feels very bureaucratic (or wait, is that a plus?)... A++ Would Do Business Again, kind of 1997 but not in a cool ironic way.
Thoughts?
