Corporate Social Bookmarking Tools : eLearning Technology

I was just asked on twitter about use social bookmarking tools that work behind the firewall. I thought I had blogged about this before, but I'm not finding the post.

Here are the social bookmarking tools that I commonly cite in presentations:

• BEA Pathways
• Cogenz
• Connectbeam
• del.irio.us - perl based, very similar to del.icio.us
• IBM Lotus Connections
• Scuttle – Open Source
• WSSsearch - SharePoint add-on

Any others? Good comparisons of these?

I originally included: Jive Software - because I thought they had it, but it appears they don't.
