People ask me, “what is the difference between a wiki and a blog?” There isn’t one easy answer, but here are several:
- The main difference between the two is that wikis are essentially dynamic websites, with a navigation structure YOU can determine. Much of the design is up to the wiki administrator/creator. A blog is a template that takes posts and puts them in reverse chronological order. Yes, you can create additional pages on a blog, but the format on the pages remains the same . . . chronological postings that allow comments.
- Also, wikis are generally better for multiple users and contributors, whereas blogs are usually meant for a single writer. However . . . you CAN create a group blog, and they sometimes work quite well. A group of students, for instance, can use a blog to post comments on a reading.
- Blogs LOOK NICER than wikis, for the most part. Blogs have an inherent structure that looks pretty darn organized and neat, whereas wikis can be a bit of a mess, especially at the beginning. But remember, wikis are unstructured sites to begin with, that develop some sort of structure over time.
- Blogs really aren’t discussion boards and shouldn’t be used as a substitute for them. Yes, one can post comments to a posting, but that is all they are . . . comments to a post. Use either a discussion forum for asynchronous discussions or use the comments feature on wiki pages if you want to start conversations.
- Wikis generate a history of page revisions, which enable you to revert to a previous page if you don’t like what someone else has done to your page. Blogs don’t do this.
- Wikis are a collection of webpages that includes any type of content . . . blogs contain postings that resemble journals or news articles.
Use a wiki for a collaborative workspace and a blog for reading and writing posts on a common theme. While they seem similar at first, they each have their own strengths and purposes. For blog examples, use the Google blog search engine: http://blogsearch.google.com and technorati http://technorati.com
I just found this Google special wiki search engine, too, so try this out and see what you think.
