There are a lot of choices of blog sites and tools. I decided to use Blogger because Google owns it, it's free, looked easy to set up, connected with Google+ so my 3 followers can easily find me:)
Bluehost only provides instructions on how to set up Wordpress, so I used these instructions instead:
To put Blogger on your site you need a subdomain. Through cpanel's domain management and Subdomains I created blog.jimcsmith.com.
Then at blogger.com you create your blog.
Next under Blogger's settings/advanced you add a 3rd party url to, in my case, blog.jimcsmith.com. Clicking the save button gives you an error message and instructions to add two CNAME entries into your host server's DNS settings.
Going back to the Blogger settings page and clicking the save button gave no errors this time. Now entering in either blog.jimcmith.com or jimcsmith1.blogspot.com brings up my blog.
