If you get a domain name and I do recommend that you do, I think you should go with Wordpress because Google loves Wordpress blogs more than they do blogger blogs. You'll also have a lot more freedom to do whatever you want.
I build most of my sites with Wordpress and I do have some blogger blogs. You can also do a landing page with
www.weebly.com as well if you cant pay for hosting.
You can structure your site any way you like as long as it has useful content that meets the needs of the end user.
By the way, keep the questions coming.
