Julian Elve describes how he uses Weblogs and Wikis together:
I’ve found the writing style that has started to evolve since I had this combination of tools is to scatter thoughts around the wiki-spaces until some juxtaposition forms that is sufficiently clear to create a blog-entry. The blog-entry becomes a picture of my thinking at a point in time and therefore essential to mapping out some kind of path. The state of the wiki pages continues to evolve — by looking where there is activity you can see which parts of my mental associations are currently to the forefront of attention.
I am on the edge of adding an overarching wiki space to the filtering blogs we use to support seminars. Thoughts like these will help to identify a good practice.
