You can customize your URL using YourBrandName.com instead of having .Blogspot.com in your blog address and still keep using Blogger platform to host your blog.
The other way of having your dot com in the shape of a blog is buying your domain and then pay for a hosting service. What we did with BloggersSchool.com was buy the domain from GoDaddy and pay for their host. We are using WordPress.org plug in to power our new blog and it has being a super interesting experience. We will keep blogging here and on BloggersSchool.WordPress.com for learning interests.
