A blog is just a website and a way to organize content. It doesn’t have to be boring crap about your personal life.
For example, I chose the blog format for my Wise Bettor website. The blog format makes it easy to add content, the content is SE friendly and it has everything I need.
The whole blog is a personal journal thing is old hat. It’s a good way to layout and organize content. Word Press is the best, in my opinion. Once you learn how it works, you can really customize it to create your own unique website–if that’s what you want.
Smart and successful business people everywhere are using blog software for their content rich websites.
