blogwagon
To blog about a current event or issue because everyone else is blogging about it. Derived from the word bandwagon which is a popular idealogy, hobby, interest that a person takes up because everyone else is doing it. Likewise, a person who jumps on the blogwagon will often do so to make themselves feel as if they are part of the community of others who have already commented on the event. It also makes them feel important because they think they have something important to say, when in reality they are simply reguritating opinions already portrayed everywhere else.
