There seems to be quite a lot of confusion over what the main purpose for a wiki is compared to that of a blog. People are using blogs as wikis, and wikis as blogs. So I thought I'd illustrate with this post.
Of course the best place to get a good overview of what a wiki is, is, ... a wiki, not a blog. Note: I'm not giving you the definition here since this is a blog, the best place for that kind of permanent information is a wiki.
I am just alerting you about it here because this is my web-log, my diary (daily ramblings, reminders, etc). I am not telling you about it because, well, check what a blog is to find out. A newsgroup, or Usenet is a good analogy of a blog. For example, I certainly don't want to search through a newsgroup to find what my annual leave entitlements are, this kind of information is better placed in a wiki.
That isn't to say you have to follow strict rules. But you should take the time to think before just putting a heap of information on a blog, or wiki. Is it a point of view (blog), or is it guidance (wiki), information (wiki), or something in between (eg this post)?
A good rule of thumb - put information on a wiki and tell people about it in a blog.
What do you think?
