It seems to me that while we have two distinct camps here we both ultimately want a platform that does the same sort of thing. Empower the citizens of the region.
My own personal preference for hierarchy is that it does provide a path. In that sense I tend to think of Taijitu, via NS, as a game first and foremost in that people are more likely to play if they see a path of advancement. You become a cabinet member, maybe take on more responsibilities, and then suddenly you're ready to run for Delegate.
It's less based on the ideological implications of a structured, hierarchal government and more on the idea that this system is what will get people engaged and interested. The Glorious Revolution's biggest drawback is its lack of reward for people who are interested in participation.
You sign up, you become a citizen, and then what? You're automatically part of the legislator. You can propose legislation and if it doesn't pass that's sort of it. You're fully empowered the moment you join. It would be like installing World of Warcraft and immediately getting a max level character with Mythic-tier gear. Sure, it would be fun for a while, but there's nothing making you want to come back.
Now that being said...AS is right re: aspects of the Glorious Revolution. Introducing a vetting process to limit participation in the legislator (ie bringing senators back) isn't something I think we need to be doing. I also agree with him that the fundamental aim of our party should be to get people excited in exercising the rights they hold under the laws put in place by the Glorious Revolution.
My point is simply that this can be done with a gameplay path that a cabinet system establishes. People can strive for that, and become active members of the legislator. This catches the eye of a Delegate candidate or two, and maybe they're in line for a position in a new administration.
I don't think we need to focus on an overly developed hierarchy at the moment though. My proposal would be as such....
One elected position, the Citizen-Delegate. They would have the right to name up to, say, four deputies who will aid them in the running of the region in whatever way the Delegate chooses. We're not focusing too much on hierarchy, but we're also promoting the idea of a clear path to engage the citizenry.
