Subject Re: Starting to document metrics monitoring system in wiki.

Are four letter words preferable to, say, REST? I think REST is nicer
(maybe with 4LW URLs and responses rather than JSON) from an
accessibility point of view. I don't see a reason we couldn't do it,
but it would be *great* to back away from the "everything by the
(kitchen?) sink" mindset in terms of features.

(I demand double lucky number one points for my sink pun. Yes, you're
welcome. ;))
