Hello Bob,

Firstly, the www.bootstrap.org web site has moved to http://130.107.1.200/
but the paperwork on the web has yet to catch up.

BTW: some of the geniology links I have found suggest that Park and Parks
trace to the same clan.  Interesting thought.  Nice to have you respond to
this thread.

Your web site comes very close to satisfying a notion I have had for a very
long time with regards to using the web as a collaborative tool for the
accretion and maintenance of human knowledge.  I plan to explore your web
site with great enthusiasm.

Many moons back, I built a version of the ID3 information theoretic tree
builder, and built on top of that a version of a Kelly rep. grid user
interface.  I had been following Mildred Shaw's work for a couple of years
at that time (around 1986) and thought then (and still think) that Kelly's
work needs to be represented as one of the several ways to construct a user
interface for knowledge work.  My whole project was written in Forth on a
Macintosh.  It worked, but it resulted in decision trees that were extremely
hard to read (translation: useless).  That project ran out of funding before
we were able to take advantage of new thinking about ID3 and improve the
results.  It will likely get revisited in my current Java-based stuff.

My reaction: very enthusiastic.
