Blogger is also one of the most popular blog hosts on the web. I currently have 2 blogs hosted here, The Bloogle AdSense Blog, and The HCG Diet Information Blog. So you can definitely have more than one.
It is important to have a blog host that allows you to customize the HTML on your blog, for SEO (Search Engine Optimization). I will go over SEO later this month. Keep in mind, you can use any blog host that you want, but this is only one that I am going to recommend today. So if you have another host that you would rather use, that's fine too. However, later this month I will show you how to monetize your blog and in my opinion Blogger is the best place to do that.
I hope this takes the guess work out of finding a blog host. Tomorrow I will go over what to consider when choosing your blog topic.
