I gave this presentation on Confluence as a Personal Wiki at the most recent Webmonday in Hanover.
Some people already told me that it looks like a marketing show for Confluence, but as I’ve mentioned in the presentation:

I love Confluence.

…and they’re not paying me any money to say that ;-)

My presentation from the Webmonday in Hanover on 16 Feb 2009, which actually made a couple of people create a Twitter account on the very same night ;-)
