Michael, your link contained a space...
It should be
http://seattletimes.nwsource.com/html/businesstechnology/134318433_askme16.html
They even named Siemens ShareNet as a working KM solution. Not bad.
I think that we should definitely open up a FAQ for a working KM solution inside openacs.
askme.com is not as complex for what I have seen by now.
Civilution was working on a KM solution, but I never heard anything of their efforts for quite a while.
Carl, will you guys be allowed to let your ShareNet-clone find it's way into openacs 4.x?
