Discussion boards, blogs, wikis, all are places where people talk about different topics. Putting stuff on the net leads to continued discussion later by some one else. The three of them have the same model, each of them is the view of that central model.
Discussion boards organize data by thread, date, author etc. But they don’t distinguish between the post and its comment. They are good in a question answer scenario.
Blogs arrange posts chronologically but always tend to link outward and don’t try to make sense of all the posts till now. The author of the blog is the one who has a mental model of all the posts. You have to read through all the posts to make sense of them. Blogs are good when used to maintain the history of events or maintain an archive.
Wikis link ideas to one another. A group of people creates a logical flow of information. The information is in context wrt to other info on the site. Wikis normally don’t have a place to comment. But any member of the group can modify and edit any page. It is useful to collaborate and maintain a set of ideas coherently.
