Post History

There should be a full moderation log visible to everyone

Each site should have a page that shows the full history of all moderator actions (such as closes and deletes). This should be visible to everyone, even users who are not logged in. To protect the privacy of moderators, the names can be anonymized to something like "Moderator 1", "Moderator 2", etc. when viewed by users who do not have sufficient privileges themselves. Timestamps can be fuzzed as well, so that instead of exact time only an approximate form (eg. "3 weeks ago") is shown to low-level users.

The benefits of this are:

* Checking on moderators is crowdsourced - the entire userbase can check their work instead of just a handful
* Discussion of moderator activity can be based on fact - people can link to the specific actions they mean
* Protects users from bad moderation
* Gives users confidence that the moderation is consistent and not arbitrary
* Provides a way for users to learn *de facto* site rules and culture, in addition to the *de jure* one

I think that currently, you can see various information about moderator actions if you have enough related privileges yourself, however, the "average user" cannot see all of this. Also, I suspect that it is built towards looking at the history of a particular post, not seeing "what the moderators have been up to lately".
