Recommend that we deprecate the tag [tag:policy] and use the tag [tag:site-policy] That will enable searching on [tag:site-policy] to return posts that articulate the policy and culture of H:SE.  That, in turn, will make it easier to refer new users to authoritative reference posts on H:SE policy.

(unless someone can identify a reason to have two overlapping tags. I don't want to maintain questions about policies other than H:SE site policy.) 

Unless there is an objection, I'll go through and add [tag:site-policy] to all questions tagged [tag:policy] As time permits, we'll remove the old tag. I've updated the tag wiki.

May need to move this to a second question, but we probably should devise some protocol to identify [tag:site-policy]  under discussion vs consensus [tag:site-policy].  The simple approach would be to use the tag [tag:discussion], and remove it after a week of no new content.  Then re-add it if/when someone raises a question.
