## What is a Blog Carnival?

Since I am posting a blog carnival on Monday, I will give an overview of the basics about blog carnivals especially to my Filipino readers.

A blog carnival is simply a collection of related blogs summarized, collated, and annotated in a single document by a carnival host. A carnival host is either a blogger, a web designer, or a wiki host.
