What is a Blog?
What is a Blog? Daily Blog Tips is trying to find a good definition for 'blog'. I like Jeremiah Owyang's definition (I posted about it here):
Blogs are like a keynote speech where the speaker (blogger) is in control of the discussion, but allows questions and comments from the audience.What I like about it is that it clearly distinguishes forums from blogs. In the diagram given by Daily Blog Tips there basically is no real distinction. One distinction between forums and blogs is that with blogs the speaker is in control.
Blogs are journals often authored by one individual, and sometimes teams. In the context of business communication, these are often used to talk with the marketplace and to join the conversation that existing external bloggers may be having.
