Weblog policy: won't work

On Auricle I found a nice article on the use (or lack of use) of weblogs in Higher Education in the UK.
A little excerpt:
"Ok, all over the UK I now hear HEI's Directors of Marketing and Communications cry, (..) ... let's do it ... let's build a blog into our Web site ... but we've got to have a really tight policy about what people can and cannot write about".
Sorryeeeee ... :) ... Won't work. "
