Can somebody please direct me to the best blog hosting site on the web? I'm interested in a free site, and with designs that are suitable for a serious business. There are so many to choose from, I don't know where to start.

For those who post an answer, can you give a reason or two as to why you prefer that particular site?

Thanks !

WordPress.com

Go to blogspot.com

or multiply.com

I like Xanga.

It's easy to use and set up and you can upgrade it if you want more.
