John,
  Based on your elaboration, it seems that our disagreement only resides in
the issue of how many basic concept representations can actually be agreed
to by a community large enough to form an effective user group for the
foundation ontology -large enough to encourage people to develop utilities
to make it easier to use, and applications to demonstrate its use.  I think
that the number is above 5000 (not including those whose agreed meaning can
be logically specified in terms of the basic terms), it seems you may have a
different number in mind.  The only way I can think of to answer the
question is to fund development of an FO in a project that can develop
associated utilities and applications, without which the exercise will be
too theoretical to provide an incentive to others to use it.  We know from
past experience that volunteer efforts are unlikely to serve the purpose,
but I am willing to participate again if any such unfunded project
materializes.    (01)
