Do you think this sort of thing makes you clever? In every idea there are implementation details. What's your point?

Unless you're saying that these things will somehow be radically harder under the proposed system, and if so say how, it doesn't need saying.

We can routinely see our politicians playing to the masses so obviously if it works it's only in a round-about fashion.
