Blog, wiki or forum?

While browsing the web in search of killer applications in the field of online competence development, I came across a whole bunch of sites and blogs about knowledge management, social networking and technology. Two of them I found particularly interesting.

The first blog by Erik Duval, a professor in the research unit on hypermedia and databases at the computer science department of the "Katholieke Universiteit Leuven". If you are interested in knowing what the academic world is doing in the field of learning and education, this is worth a click.. plenty of slide shows and interesting reflexions.

The second blog is from Tommi Ryyppö. Tommi is VP business development at Dicole, a company that provides social software and consultation for organizations adopting digital knowledge working environments.

In his master thesis (link to pdf) I found an interesting comparison of blogs, wikis and discussion forums.

In discussions with clients there is often the question "Do I need a blog or a forum?" This comparison might be a nice first help.
