Abstract

A blog service company provides a function named BlogCast that exposes quality posts on the blog main page to vitalize a blogosphere. This paper analyzes a new type of information diffusion via BlogCast. We show that there exists a strong halo effect in a blogosphere via thorough investigation on a huge volume of blog data.
