I'm not sure Steve's representation of academics who work on the 'pedia
is fair or accurate. Contributions by what he called "deadwood" are
correctible - which is what lots of us do. What makes academics leave
is when it becomes clear that popular opinion often outweighs merit, and
that many people see a (false, IMO, but supported by many) dichotomy
between high standards and open content.
