About Google Blogger
Google Blogger is a free blogging service offered by Google. A blog could be defined as a shared on-line journal, where users can make comments on your blogs. Images are often posted on blogs with some descriptive text.
A Google Blog is created and managed through a Content Management System (CSM) where comments and users are managed.
You can customise you blog with templates that make it easy to get the look and feel you are looking for. There are also many free templates offered from sources other than Google.
