Blogger is a blog-publishing service that allows multi-user blogs with time-stamped entries. It was developed by Pyra Labs, which was bought by Google in 2003. Generally, the blogs are hosted by Google at a subdomain of blogspot.com. Blogs can also be hosted in the registered custom domain of the blogger (like
www.example.com).[4] A user can have up to 100 blogs per account.[5](Lifted from Wiki)
So there you have it.
And I am still non the wiser.
