I'm not sure I totally understand the contention that a policy is only worth having if you can be blocked for violating it. How many blocks are issued for violating AGF or NPOV? A policy or a guideline - but not an essay. Personally I'd prefer a policy, because it has the weight of consensus behind it and thus amounts to stronger encouragement than a simple essay from someone few have ever heard of.
As far as a separate noticeboard - I think we have noticeboard proliferationitis as it is. Someone mentioned RSN yesterday and an admin had no idea what it was, so I think that demonstrates the limited utility of yet another reports noticeboard.
