Someone did a collection of tools that combine Wikis with Weblogs. I am very interested in this approach. But I have not yet seen a site that really shows how this can be superior to a seperate Wiki plus Weblog. A weblog often contains a lot of commentary (or quotes) while WiKis are more about timeless encyclopedic collections.
Socialtext seems to work this way. Unfortunatly I couldn’t figure out if this software works better with particular writing strategies applied. I suppose I need to set up an experiment to figure that out.
Here is a guy thinking about using COREBlog in a school setting.
