Intranet info management system

[Beth Tang]

Greetings and please excuse the cross-posting.

I've been asked to help some colleagues in a new area.  What options --
ranging from "Yugo" to "Cadillac" -- would you recommend for intranet
content management/knowledge management systems?  Are there any case studies
online for lessons learned?

The context is for library and info tech, including help desk/technical
assistance, staff to share information across product lines, contacts, and
"hot" items or issues.  Comfort level with technology varies.  Should
updates be funneled to individual content managers or should everyone update
as needed?

Prefer real world examples, but marketing info ok, too.  Please reply to me
offlist at tangb at calib.com.  I'll post a summary if there's interest.

Thanks very much.
