Reason for blogs in the business world

I think one of the main reasons blogs can/are used quite often in the business world is their potential efficiency. They have the potential to save money, create effective conversation without verbal communication, and they are a great way for advertising to people within the company or even outside. I also think blogs are great for businesses because they prove that technology can be a gateway to success in the business world. I think a lot of companies rely on the fundamental forms of communication when the way of the world both in the business sector and in the social sector are evolving more and more into using computers to communicate in a "paperless" way.
