From over 1,400 postings there were only 374 attempts to
define the purpose, the rest, whilst interesting, was the normal (mostly
harmless) cut and thrust of argument, counter argument, misunderstanding, joke,
etc, etc, etc.
This is a word cloud generated from the raw text of those
374 postings, before any detailed analysis has taken place. Although some
things stand out it is a confusing picture. You can see why someone listening
to all of those people and their postings could easily get confused about what
the purpose of Enterprise Architecture was.
