Hi Brandon - I have also been working on adding custom fields support
recently, so I appreciate you raising some of these good questions.
I hadn't even considered the fact that WordPress.com doesn't support
them out of the box. This raises the question ... doesn't it seem
likely (or at least possible) that WordPress.com will add support for
custom fields, perhaps for its paying users, at some point in the
future? It doesn't look like custom fields support is currently
identified in the wlwmanifest, so maybe we should request that this
information be added.
That said, in the short term, because I expect/hope other blog systems
will adopt WordPress's conventions for Custom Fields, and because I
think Custom Fields are generally an advanced "power-user" feature,
I'm thinking I'll make it possible for any MovableType-variant blog to
be configured with custom fields support, leaving it to the user to
ensure that the configuration yields a meaningful result.
As far as I know the _prefixed custom fields are all intended to be
filtered out of the UI. I'm tentatively planning that MarsEdit should
also filter them from the UI, and furthermore avoid re-sending them
(because it could be sending an outdated value). I'm relying on the
apparent "lazy" behavior of custom fields in WordPress. That is, an
unspecified value is nondestructive. I'm hoping other blog systems
will adopt the same conventions so that omission of any particular
custom field does not indicate deletion.
