From the man who got fired from Google for Blogging

“i think blogging is the next big thing on the internet. the web gave people revolutionary access to information; email and instant messaging disrupted the way people communicate with each other; blogging empowers everyone to create new information and connect in a community. it�s the culmination of lots of the progress that has happened on the internet rolled into one huge, powerful, killer app. corporations should embrace this technology just like the ones before it. companies that are confident in their offerings should let employees spread the word. in today’s age of information overload, blogging is quickly emerging as the fastest and most cost-effective method of marketing.”

Blogging does empower people to express their views publically to millions. It’s quite empowering and potentially dangereous for the Blogger.
