It's good to see others who are interested in sharing their experiences with the world!
As a new blogger, I would suggest that you use a free blog domain through wordpress first, and then after you have gotten the feel for blogging you can move on to more complicated things - such as buying a domain name and creating a personalized blog.
1) Go to
WordPress.com » Get a Free Blog Here
2) Sign up and follow the steps
3) Start blogging.
Good luck!
