BEWARE - this is a case of shameless self-promotion ! If you don't like it do NOT read on.
InsightKnowledge Inc. to the best of its capabilities is linking to KM job posting whereever it can find them. If you are looking for one place to look for Knowledge Management job postings/offerings, this may be it.
You do have to register for free, but that's it for the basic personal Knowledge Management functionality. If you wish to expand into group knowledge networks, its only $5/month a network for a knowledge subscription.
That's it - now I am done (for a while) :-).
