Good questions. We've made a start at providing an ultra-simple
explanation on the licenses page itself:

<http://www.opendatacommons.org/licenses/>

This now says:

<quote>
    * Public Domain Dedication and License
          o When using the PDDL you may wish to associate a set of
Community Norms.
    * Open Database License —  "Attribution/Share-Alike for databases"
    * Factual Information License — "MIT/BSD for factual information"
</quote>

There isn't an explanatory sentence for the PDDL since the name seems
self-explanatory but if we could add something like: "Put your
database in the public domain"

It has also been suggested that we should have a brief header to each
'license' giving a human readable summary a la Creative Commons.
However the licenses already have a 'human-readable' preamble (a la
the GPL) and so I'm not sure how much benefit this would produce
(though we could make the preambles more prominent).
