Blogswarms can happen around many different kinds of things. For example, there may be a big industry change, such as a shift in automotive manufacturing. Industry bloggers, and even others outside the industry, might jump on in and start reporting on it in blogs. Sometimes, blogswarms happen around controversial political events, such as a prominent murder trial, or political turmoil in a certain country.
