After our presentation, someone (I can’t remember who!) asked the question “I’m starting a project, which should I use: A blog or a wiki?”
The questions kind of took me aback, and I’m afraid I answered rather ineptly. To me, the difference are pretty clear, but I couldn’t, on the spur of the moment, articulate that into a soundbite. After thinking about it for several weeks, I think I have a bit of an answer:
Use a wiki if you need to create information collaboratively. Use a blog if you only need to disseminate it.
This question is something I am considering doing a poster presentation on- mostly because I think I can come up with some nice visuals to go with it. I was thinking a mindmap looking thing that shows the structure of a blog opposed to the amorphous quality of a wiki.
