Why should moderators' user cards show a diamond (♦︎︎︎) when they post a question or answer or comment?
I don't mean "why do they" -- the answer to which is, "because they're moderators" -- but why should they, i.e. why is that a good thing, and isn't it a bad thing i.e. a source of confusion and noise?
Aren't moderators simply like other users, not especially authoritative about the suject matter?
Instead why isn't the ("official") diamond shown:
- Always-but-only on Meta (not on the main site)
- Never in Qs and As on the main site
- Only sometimes i.e. optionally in comments on the main site, i.e. when posting an official comment in their capacity as moderator, rather than e.g. posting a comment about content as any other user might?
Disclosure: I am a site moderator of a small site.
