Forums are like social mixers, where everyone is at equal level, milling about and discussing with others. These many to many communication tools allow anyone to start a topic and anyone to respond to one. Members are often at equal level, and content is usually segmented by topic. Blogs are like a keynote speech where the speaker (blogger) is in control of the discussion, but allows questions and comments from the audience. Blogs are journals often authored by one individual, and sometimes teams.
