I think we need other buttons to express a degree of interest, such as
"Awful", "Poor", "Fair", "Good", "Great"

Seals Of APproval are a must have feature for discussion tools.

See the WIT entry I put in on peer review schemes.

Meanwhile I have implemented persistent object support for general review

It is UNWISE to commit mechanism to a FIXED scheme because there is a large
universe of possibilities here, and no clear criteria for universally
preferring a specific one.

It would be better to provide GENERAL mechanism that can support ARBITRARY
schemes but provide some basic examples for initial use.

So what you want is:

REFERENCE: message-id|urn|url|...

REVIEW-SCHEME: <scheme-name>

REVIEW: <scheme-specific value>

So, you can consider the RESCHERIAN-scheme (agree/disagree) to have five
values, from 1 to 5, with mappings to "Awful", "Poor", "median" "Good",
"Great" You can then center on the midpoint and perform numeric operations to
weight opinions...

If anybody cares about this, we can go into more detail.
