I realize I am straying from the main subject of this thread, but I wanted to ask a question based on what was said above. When a new proposal (in whatever area) is presented, how and where is the final decision made as to whether that proposal becomes policy or not; and who ultimately makes it?
If consensus is reached, it's up to pretty much anyone to carry it out. If it turns out there wasn't consensus then we'll find out when someone reverts the changes.
Policy is determined in pretty much the same way as content in articles. It keeps getting changed until everyone is happy with (or at least willing to accept) what we've got. The principle of "Be Bold" isn't applied so much to policy - it's usual to discuss changes before you make them, rather than making them and seeing if any reverts and only discussing it if they do, but the basic process is the same.
