CNN has a story that is a great validation for the growing popularity of blogs.  Merriam Webster, a famous dictionary publisher, claims that the word "blog" is their top word of the year, based on total number of web searches.  As a result, the word BLOG will be added to the 2005 version of the Merriam-Webster Collegiate Dictionary.

Note: The complete list of words of the year is available at the Merriam-Webster site.
