Bloggeris a great, easy to use site for creating a personal blog. However, if you are planning to build a blog for business purposes, it is probably not your best choice, even to start out on. I just learned that Google does not allow Blogger sites to 301 redirect. What this means is that if you are successful in building up good page rank and back links to your Blogger site, and then later decide to move it to another domain, you will lose all of the SEO “juice” you had built up on the Blogger site.

For this reason and others, we’re planning to move off of Blogger very soon, before we’ve put any more effort into building it up.
