A forum is an exchange of written “conversations” amongst group members. One participant might publish a brief question or comment on a subject of interest to the group in a forum, for instance. After reading the forum issue, other users submit a comment with a response or a viewpoint on it. A forum is essentially a technique to gather various viewpoints on a particular issue.
A blog is quite unique. A blog is typically a platform where one person expresses their opinions on a specific subject. Similar to an essay, blog postings are often longer (several paragraphs) and feature the author’s stated perspective. In a blog, the blogger puts forward an idea, and others can comment on it, but there is no real discussion.
