Blogger

I am interested in starting a blog, I have never blogged before, have a dedicated server running our business sites and mostly use Joomla CMS.

how to go about building the blog, our mission with the blog is for supporting our primary business, we ultimately want site visitors and lots of them to the blog. So not sure if going with something like domain.blogspot.com is better.

So, do I go with a blogging service(if yes, blogger ... which one?)or do I build a custom blog using Joomla?

Any help here would be great, I am ready to go but keep stopping short feeling unsure of the committment.
